Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553764, here are decompositions:

3 + 31553761 = 31553764
5 + 31553759 = 31553764
101 + 31553663 = 31553764
311 + 31553453 = 31553764
443 + 31553321 = 31553764
491 + 31553273 = 31553764
503 + 31553261 = 31553764
563 + 31553201 = 31553764

Showing the first eight; more decompositions exist.
