Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565482, here are decompositions:

59 + 31565423 = 31565482
71 + 31565411 = 31565482
83 + 31565399 = 31565482
131 + 31565351 = 31565482
173 + 31565309 = 31565482
191 + 31565291 = 31565482
233 + 31565249 = 31565482
251 + 31565231 = 31565482

Showing the first eight; more decompositions exist.
