Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552846, here are decompositions:

29 + 31552817 = 31552846
113 + 31552733 = 31552846
137 + 31552709 = 31552846
257 + 31552589 = 31552846
293 + 31552553 = 31552846
359 + 31552487 = 31552846
443 + 31552403 = 31552846
593 + 31552253 = 31552846

Showing the first eight; more decompositions exist.
