Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552892, here are decompositions:

13 + 31552879 = 31552892
61 + 31552831 = 31552892
199 + 31552693 = 31552892
211 + 31552681 = 31552892
271 + 31552621 = 31552892
313 + 31552579 = 31552892
463 + 31552429 = 31552892
499 + 31552393 = 31552892

Showing the first eight; more decompositions exist.
