Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502624, here are decompositions:

37 + 31502587 = 31502624
61 + 31502563 = 31502624
67 + 31502557 = 31502624
193 + 31502431 = 31502624
271 + 31502353 = 31502624
313 + 31502311 = 31502624
337 + 31502287 = 31502624
463 + 31502161 = 31502624

Showing the first eight; more decompositions exist.
