Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553294, here are decompositions:

61 + 31553233 = 31553294
277 + 31553017 = 31553294
463 + 31552831 = 31553294
547 + 31552747 = 31553294
601 + 31552693 = 31553294
613 + 31552681 = 31553294
673 + 31552621 = 31553294
691 + 31552603 = 31553294

Showing the first eight; more decompositions exist.
