Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514588, here are decompositions:

37 + 31514551 = 31514588
109 + 31514479 = 31514588
139 + 31514449 = 31514588
349 + 31514239 = 31514588
367 + 31514221 = 31514588
397 + 31514191 = 31514588
439 + 31514149 = 31514588
487 + 31514101 = 31514588

Showing the first eight; more decompositions exist.
