Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537388, here are decompositions:

61 + 31537327 = 31537388
79 + 31537309 = 31537388
241 + 31537147 = 31537388
349 + 31537039 = 31537388
397 + 31536991 = 31537388
541 + 31536847 = 31537388
691 + 31536697 = 31537388
859 + 31536529 = 31537388

Showing the first eight; more decompositions exist.
