Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455074, here are decompositions:

  • 3 + 31455071 = 31455074
  • 43 + 31455031 = 31455074
  • 103 + 31454971 = 31455074
  • 151 + 31454923 = 31455074
  • 193 + 31454881 = 31455074
  • 337 + 31454737 = 31455074
  • 373 + 31454701 = 31455074
  • 421 + 31454653 = 31455074

Showing the first eight; more decompositions exist.
