Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528964, here are decompositions:

151 + 31528813 = 31528964
157 + 31528807 = 31528964
163 + 31528801 = 31528964
223 + 31528741 = 31528964
241 + 31528723 = 31528964
331 + 31528633 = 31528964
433 + 31528531 = 31528964
463 + 31528501 = 31528964

Showing the first eight; more decompositions exist.
