Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626284, here are decompositions:

37 + 31626247 = 31626284
211 + 31626073 = 31626284
331 + 31625953 = 31626284
367 + 31625917 = 31626284
373 + 31625911 = 31626284
463 + 31625821 = 31626284
523 + 31625761 = 31626284
631 + 31625653 = 31626284

Showing the first eight; more decompositions exist.
