Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972178, here are decompositions:

  • 31 + 4294972147 = 4294972178
  • 61 + 4294972117 = 4294972178
  • 109 + 4294972069 = 4294972178
  • 127 + 4294972051 = 4294972178
  • 139 + 4294972039 = 4294972178
  • 241 + 4294971937 = 4294972178
  • 337 + 4294971841 = 4294972178
  • 349 + 4294971829 = 4294972178

Showing the first eight; more decompositions exist.
