Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486652, here are decompositions:

13 + 31486639 = 31486652
19 + 31486633 = 31486652
103 + 31486549 = 31486652
199 + 31486453 = 31486652
229 + 31486423 = 31486652
313 + 31486339 = 31486652
349 + 31486303 = 31486652
523 + 31486129 = 31486652

Showing the first eight; more decompositions exist.
