Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506274, here are decompositions:

  • 3 + 31506271 = 31506274
  • 11 + 31506263 = 31506274
  • 101 + 31506173 = 31506274
  • 281 + 31505993 = 31506274
  • 347 + 31505927 = 31506274
  • 353 + 31505921 = 31506274
  • 431 + 31505843 = 31506274
  • 461 + 31505813 = 31506274

Showing the first eight; more decompositions exist.
