Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552632, here are decompositions:

11 + 31552621 = 31552632
29 + 31552603 = 31552632
43 + 31552589 = 31552632
53 + 31552579 = 31552632
79 + 31552553 = 31552632
211 + 31552421 = 31552632
229 + 31552403 = 31552632
239 + 31552393 = 31552632

Showing the first eight; more decompositions exist.
