Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610754, here are decompositions:

13 + 31610741 = 31610754
31 + 31610723 = 31610754
47 + 31610707 = 31610754
113 + 31610641 = 31610754
167 + 31610587 = 31610754
173 + 31610581 = 31610754
181 + 31610573 = 31610754
191 + 31610563 = 31610754

Showing the first eight; more decompositions exist.
