Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552662, here are decompositions:

19 + 31552643 = 31552662
23 + 31552639 = 31552662
41 + 31552621 = 31552662
59 + 31552603 = 31552662
73 + 31552589 = 31552662
83 + 31552579 = 31552662
109 + 31552553 = 31552662
173 + 31552489 = 31552662

Showing the first eight; more decompositions exist.
