Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607348, here are decompositions:

7 + 31607341 = 31607348
67 + 31607281 = 31607348
211 + 31607137 = 31607348
397 + 31606951 = 31607348
607 + 31606741 = 31607348
691 + 31606657 = 31607348
769 + 31606579 = 31607348
811 + 31606537 = 31607348

Showing the first eight; more decompositions exist.
