Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535576, here are decompositions:

73 + 31535503 = 31535576
109 + 31535467 = 31535576
157 + 31535419 = 31535576
199 + 31535377 = 31535576
313 + 31535263 = 31535576
349 + 31535227 = 31535576
433 + 31535143 = 31535576
463 + 31535113 = 31535576

Showing the first eight; more decompositions exist.
