Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552722, here are decompositions:

13 + 31552709 = 31552722
29 + 31552693 = 31552722
41 + 31552681 = 31552722
79 + 31552643 = 31552722
83 + 31552639 = 31552722
101 + 31552621 = 31552722
233 + 31552489 = 31552722
293 + 31552429 = 31552722

Showing the first eight; more decompositions exist.
