Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553276, here are decompositions:

3 + 31553273 = 31553276
43 + 31553233 = 31553276
199 + 31553077 = 31553276
277 + 31552999 = 31553276
397 + 31552879 = 31553276
673 + 31552603 = 31553276
739 + 31552537 = 31553276
787 + 31552489 = 31553276

Showing the first eight; more decompositions exist.
