Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497412, here are decompositions:

3 + 31497409 = 31497412
53 + 31497359 = 31497412
59 + 31497353 = 31497412
71 + 31497341 = 31497412
113 + 31497299 = 31497412
449 + 31496963 = 31497412
491 + 31496921 = 31497412
593 + 31496819 = 31497412

Showing the first eight; more decompositions exist.
