Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523746, here are decompositions:

113 + 31523633 = 31523746
167 + 31523579 = 31523746
269 + 31523477 = 31523746
347 + 31523399 = 31523746
467 + 31523279 = 31523746
479 + 31523267 = 31523746
503 + 31523243 = 31523746
509 + 31523237 = 31523746

Showing the first eight; more decompositions exist.
