Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552876, here are decompositions:

23 + 31552853 = 31552876
29 + 31552847 = 31552876
59 + 31552817 = 31552876
149 + 31552727 = 31552876
167 + 31552709 = 31552876
233 + 31552643 = 31552876
389 + 31552487 = 31552876
647 + 31552229 = 31552876

Showing the first eight; more decompositions exist.
