Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607282, here are decompositions:

19 + 31607263 = 31607282
181 + 31607101 = 31607282
331 + 31606951 = 31607282
379 + 31606903 = 31607282
541 + 31606741 = 31607282
571 + 31606711 = 31607282
601 + 31606681 = 31607282
631 + 31606651 = 31607282

Showing the first eight; more decompositions exist.
