Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552756, here are decompositions:

23 + 31552733 = 31552756
29 + 31552727 = 31552756
47 + 31552709 = 31552756
113 + 31552643 = 31552756
167 + 31552589 = 31552756
269 + 31552487 = 31552756
353 + 31552403 = 31552756
503 + 31552253 = 31552756

Showing the first eight; more decompositions exist.
