Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610648, here are decompositions:

7 + 31610641 = 31610648
19 + 31610629 = 31610648
61 + 31610587 = 31610648
67 + 31610581 = 31610648
79 + 31610569 = 31610648
109 + 31610539 = 31610648
127 + 31610521 = 31610648
211 + 31610437 = 31610648

Showing the first eight; more decompositions exist.
