Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552684, here are decompositions:

3 + 31552681 = 31552684
41 + 31552643 = 31552684
131 + 31552553 = 31552684
197 + 31552487 = 31552684
263 + 31552421 = 31552684
281 + 31552403 = 31552684
431 + 31552253 = 31552684
491 + 31552193 = 31552684

Showing the first eight; more decompositions exist.
