Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497334, here are decompositions:

41 + 31497293 = 31497334
47 + 31497287 = 31497334
83 + 31497251 = 31497334
251 + 31497083 = 31497334
263 + 31497071 = 31497334
461 + 31496873 = 31497334
593 + 31496741 = 31497334
641 + 31496693 = 31497334

Showing the first eight; more decompositions exist.
