Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607048, here are decompositions:

97 + 31606951 = 31607048
307 + 31606741 = 31607048
337 + 31606711 = 31607048
367 + 31606681 = 31607048
397 + 31606651 = 31607048
619 + 31606429 = 31607048
661 + 31606387 = 31607048
709 + 31606339 = 31607048

Showing the first eight; more decompositions exist.
