Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537362, here are decompositions:

23 + 31537339 = 31537362
53 + 31537309 = 31537362
89 + 31537273 = 31537362
139 + 31537223 = 31537362
211 + 31537151 = 31537362
229 + 31537133 = 31537362
313 + 31537049 = 31537362
359 + 31537003 = 31537362

Showing the first eight; more decompositions exist.
