Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610874, here are decompositions:

7 + 31610867 = 31610874
83 + 31610791 = 31610874
101 + 31610773 = 31610874
103 + 31610771 = 31610874
151 + 31610723 = 31610874
167 + 31610707 = 31610874
233 + 31610641 = 31610874
293 + 31610581 = 31610874

Showing the first eight; more decompositions exist.
