Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535264, here are decompositions:

31 + 31535233 = 31535264
37 + 31535227 = 31535264
151 + 31535113 = 31535264
157 + 31535107 = 31535264
181 + 31535083 = 31535264
283 + 31534981 = 31535264
433 + 31534831 = 31535264
463 + 31534801 = 31535264

Showing the first eight; more decompositions exist.
