Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450892, here are decompositions:

13 + 31450879 = 31450892
103 + 31450789 = 31450892
271 + 31450621 = 31450892
313 + 31450579 = 31450892
349 + 31450543 = 31450892
409 + 31450483 = 31450892
463 + 31450429 = 31450892
523 + 31450369 = 31450892

Showing the first eight; more decompositions exist.
