Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573608, here are decompositions:

  • 37 + 31573571 = 31573608
  • 47 + 31573561 = 31573608
  • 107 + 31573501 = 31573608
  • 109 + 31573499 = 31573608
  • 181 + 31573427 = 31573608
  • 251 + 31573357 = 31573608
  • 331 + 31573277 = 31573608
  • 347 + 31573261 = 31573608

Showing the first eight; more decompositions exist.
