Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573544, here are decompositions:

  • 31 + 31573513 = 31573544
  • 43 + 31573501 = 31573544
  • 151 + 31573393 = 31573544
  • 181 + 31573363 = 31573544
  • 283 + 31573261 = 31573544
  • 421 + 31573123 = 31573544
  • 433 + 31573111 = 31573544
  • 487 + 31573057 = 31573544

Showing the first eight; more decompositions exist.
