Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607530, here are decompositions:

41 + 31607489 = 31607530
83 + 31607447 = 31607530
107 + 31607423 = 31607530
131 + 31607399 = 31607530
167 + 31607363 = 31607530
173 + 31607357 = 31607530
233 + 31607297 = 31607530
239 + 31607291 = 31607530

Showing the first eight; more decompositions exist.
