Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529058, here are decompositions:

  • 5 + 31529053 = 31529058
  • 61 + 31528997 = 31529058
  • 89 + 31528969 = 31529058
  • 149 + 31528909 = 31529058
  • 227 + 31528831 = 31529058
  • 251 + 31528807 = 31529058
  • 257 + 31528801 = 31529058
  • 307 + 31528751 = 31529058

Showing the first eight; more decompositions exist.
