Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972100, here are decompositions:

  • 7 + 4294972093 = 4294972100
  • 31 + 4294972069 = 4294972100
  • 37 + 4294972063 = 4294972100
  • 61 + 4294972039 = 4294972100
  • 109 + 4294971991 = 4294972100
  • 157 + 4294971943 = 4294972100
  • 163 + 4294971937 = 4294972100
  • 241 + 4294971859 = 4294972100

Showing the first eight; more decompositions exist.
