Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552426, here are decompositions:

5 + 31552421 = 31552426
23 + 31552403 = 31552426
173 + 31552253 = 31552426
197 + 31552229 = 31552426
233 + 31552193 = 31552426
449 + 31551977 = 31552426
467 + 31551959 = 31552426
569 + 31551857 = 31552426

Showing the first eight; more decompositions exist.
