Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523614, here are decompositions:

137 + 31523477 = 31523614
173 + 31523441 = 31523614
233 + 31523381 = 31523614
347 + 31523267 = 31523614
383 + 31523231 = 31523614
503 + 31523111 = 31523614
587 + 31523027 = 31523614
593 + 31523021 = 31523614

Showing the first eight; more decompositions exist.
