Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529324, here are decompositions:

3 + 31529321 = 31529324
67 + 31529257 = 31529324
157 + 31529167 = 31529324
271 + 31529053 = 31529324
331 + 31528993 = 31529324
523 + 31528801 = 31529324
601 + 31528723 = 31529324
691 + 31528633 = 31529324

Showing the first eight; more decompositions exist.
