Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528848, here are decompositions:

  • 5 + 31528843 = 31528848
  • 7 + 31528841 = 31528848
  • 17 + 31528831 = 31528848
  • 37 + 31528811 = 31528848
  • 41 + 31528807 = 31528848
  • 47 + 31528801 = 31528848
  • 97 + 31528751 = 31528848
  • 107 + 31528741 = 31528848

Showing the first eight; more decompositions exist.
