Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553528, here are decompositions:

367 + 31553161 = 31553528
439 + 31553089 = 31553528
907 + 31552621 = 31553528
991 + 31552537 = 31553528
1039 + 31552489 = 31553528
1291 + 31552237 = 31553528
1321 + 31552207 = 31553528
1459 + 31552069 = 31553528

Showing the first eight; more decompositions exist.
