Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553264, here are decompositions:

3 + 31553261 = 31553264
31 + 31553233 = 31553264
103 + 31553161 = 31553264
373 + 31552891 = 31553264
433 + 31552831 = 31553264
571 + 31552693 = 31553264
643 + 31552621 = 31553264
661 + 31552603 = 31553264

Showing the first eight; more decompositions exist.
