Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473962, here are decompositions:

  • 31 + 31473931 = 31473962
  • 61 + 31473901 = 31473962
  • 151 + 31473811 = 31473962
  • 181 + 31473781 = 31473962
  • 229 + 31473733 = 31473962
  • 379 + 31473583 = 31473962
  • 433 + 31473529 = 31473962
  • 439 + 31473523 = 31473962

Showing the first eight; more decompositions exist.
