Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489766, here are decompositions:

13 + 31489753 = 31489766
19 + 31489747 = 31489766
43 + 31489723 = 31489766
103 + 31489663 = 31489766
277 + 31489489 = 31489766
349 + 31489417 = 31489766
367 + 31489399 = 31489766
487 + 31489279 = 31489766

Showing the first eight; more decompositions exist.
