Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552710, here are decompositions:

17 + 31552693 = 31552710
29 + 31552681 = 31552710
67 + 31552643 = 31552710
71 + 31552639 = 31552710
89 + 31552621 = 31552710
107 + 31552603 = 31552710
131 + 31552579 = 31552710
157 + 31552553 = 31552710

Showing the first eight; more decompositions exist.
