Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610670, here are decompositions:

29 + 31610641 = 31610670
31 + 31610639 = 31610670
41 + 31610629 = 31610670
83 + 31610587 = 31610670
89 + 31610581 = 31610670
97 + 31610573 = 31610670
101 + 31610569 = 31610670
107 + 31610563 = 31610670

Showing the first eight; more decompositions exist.
