Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552906, here are decompositions:

23 + 31552883 = 31552906
53 + 31552853 = 31552906
59 + 31552847 = 31552906
89 + 31552817 = 31552906
173 + 31552733 = 31552906
179 + 31552727 = 31552906
197 + 31552709 = 31552906
263 + 31552643 = 31552906

Showing the first eight; more decompositions exist.
