Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473590, here are decompositions:

  • 7 + 31473583 = 31473590
  • 61 + 31473529 = 31473590
  • 67 + 31473523 = 31473590
  • 103 + 31473487 = 31473590
  • 193 + 31473397 = 31473590
  • 277 + 31473313 = 31473590
  • 307 + 31473283 = 31473590
  • 349 + 31473241 = 31473590

Showing the first eight; more decompositions exist.
