Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552304, here are decompositions:

67 + 31552237 = 31552304
97 + 31552207 = 31552304
271 + 31552033 = 31552304
307 + 31551997 = 31552304
367 + 31551937 = 31552304
523 + 31551781 = 31552304
547 + 31551757 = 31552304
571 + 31551733 = 31552304

Showing the first eight; more decompositions exist.
