Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607746, here are decompositions:

29 + 31607717 = 31607746
59 + 31607687 = 31607746
167 + 31607579 = 31607746
257 + 31607489 = 31607746
347 + 31607399 = 31607746
383 + 31607363 = 31607746
389 + 31607357 = 31607746
419 + 31607327 = 31607746

Showing the first eight; more decompositions exist.
