Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526044, here are decompositions:

23 + 31526021 = 31526044
131 + 31525913 = 31526044
227 + 31525817 = 31526044
233 + 31525811 = 31526044
257 + 31525787 = 31526044
281 + 31525763 = 31526044
443 + 31525601 = 31526044
491 + 31525553 = 31526044

Showing the first eight; more decompositions exist.
