Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474040, here are decompositions:

  • 7 + 31474033 = 31474040
  • 109 + 31473931 = 31474040
  • 139 + 31473901 = 31474040
  • 193 + 31473847 = 31474040
  • 229 + 31473811 = 31474040
  • 307 + 31473733 = 31474040
  • 337 + 31473703 = 31474040
  • 457 + 31473583 = 31474040

Showing the first eight; more decompositions exist.
