Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607762, here are decompositions:

73 + 31607689 = 31607762
79 + 31607683 = 31607762
163 + 31607599 = 31607762
181 + 31607581 = 31607762
211 + 31607551 = 31607762
313 + 31607449 = 31607762
421 + 31607341 = 31607762
463 + 31607299 = 31607762

Showing the first eight; more decompositions exist.
