Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610884, here are decompositions:

17 + 31610867 = 31610884
113 + 31610771 = 31610884
311 + 31610573 = 31610884
491 + 31610393 = 31610884
521 + 31610363 = 31610884
593 + 31610291 = 31610884
647 + 31610237 = 31610884
653 + 31610231 = 31610884

Showing the first eight; more decompositions exist.
