Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497766, here are decompositions:

29 + 31497737 = 31497766
59 + 31497707 = 31497766
197 + 31497569 = 31497766
239 + 31497527 = 31497766
317 + 31497449 = 31497766
467 + 31497299 = 31497766
479 + 31497287 = 31497766
683 + 31497083 = 31497766

Showing the first eight; more decompositions exist.
