Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528262, here are decompositions:

151 + 31528111 = 31528262
193 + 31528069 = 31528262
331 + 31527931 = 31528262
349 + 31527913 = 31528262
433 + 31527829 = 31528262
739 + 31527523 = 31528262
919 + 31527343 = 31528262
1009 + 31527253 = 31528262

Showing the first eight; more decompositions exist.
