Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552582, here are decompositions:

3 + 31552579 = 31552582
29 + 31552553 = 31552582
179 + 31552403 = 31552582
311 + 31552271 = 31552582
353 + 31552229 = 31552582
389 + 31552193 = 31552582
443 + 31552139 = 31552582
563 + 31552019 = 31552582

Showing the first eight; more decompositions exist.
