Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565362, here are decompositions:

11 + 31565351 = 31565362
53 + 31565309 = 31565362
71 + 31565291 = 31565362
83 + 31565279 = 31565362
113 + 31565249 = 31565362
131 + 31565231 = 31565362
233 + 31565129 = 31565362
293 + 31565069 = 31565362

Showing the first eight; more decompositions exist.
