Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552732, here are decompositions:

5 + 31552727 = 31552732
11 + 31552721 = 31552732
23 + 31552709 = 31552732
89 + 31552643 = 31552732
179 + 31552553 = 31552732
311 + 31552421 = 31552732
461 + 31552271 = 31552732
479 + 31552253 = 31552732

Showing the first eight; more decompositions exist.
