Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552770, here are decompositions:

23 + 31552747 = 31552770
37 + 31552733 = 31552770
43 + 31552727 = 31552770
61 + 31552709 = 31552770
89 + 31552681 = 31552770
127 + 31552643 = 31552770
131 + 31552639 = 31552770
149 + 31552621 = 31552770

Showing the first eight; more decompositions exist.
