Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552798, here are decompositions:

71 + 31552727 = 31552798
89 + 31552709 = 31552798
311 + 31552487 = 31552798
569 + 31552229 = 31552798
587 + 31552211 = 31552798
659 + 31552139 = 31552798
821 + 31551977 = 31552798
839 + 31551959 = 31552798

Showing the first eight; more decompositions exist.
