Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528092, here are decompositions:

  • 23 + 31528069 = 31528092
  • 73 + 31528019 = 31528092
  • 151 + 31527941 = 31528092
  • 179 + 31527913 = 31528092
  • 263 + 31527829 = 31528092
  • 311 + 31527781 = 31528092
  • 383 + 31527709 = 31528092
  • 389 + 31527703 = 31528092

Showing the first eight; more decompositions exist.
