Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607718, here are decompositions:

29 + 31607689 = 31607718
31 + 31607687 = 31607718
47 + 31607671 = 31607718
89 + 31607629 = 31607718
137 + 31607581 = 31607718
139 + 31607579 = 31607718
167 + 31607551 = 31607718
229 + 31607489 = 31607718

Showing the first eight; more decompositions exist.
