Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448194, here are decompositions:

  • 3 + 31448191 = 31448194
  • 23 + 31448171 = 31448194
  • 53 + 31448141 = 31448194
  • 83 + 31448111 = 31448194
  • 137 + 31448057 = 31448194
  • 227 + 31447967 = 31448194
  • 233 + 31447961 = 31448194
  • 263 + 31447931 = 31448194

Showing the first eight; more decompositions exist.
