Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552866, here are decompositions:

13 + 31552853 = 31552866
19 + 31552847 = 31552866
139 + 31552727 = 31552866
157 + 31552709 = 31552866
173 + 31552693 = 31552866
223 + 31552643 = 31552866
227 + 31552639 = 31552866
263 + 31552603 = 31552866

Showing the first eight; more decompositions exist.
