Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610678, here are decompositions:

37 + 31610641 = 31610678
97 + 31610581 = 31610678
109 + 31610569 = 31610678
139 + 31610539 = 31610678
157 + 31610521 = 31610678
241 + 31610437 = 31610678
409 + 31610269 = 31610678
571 + 31610107 = 31610678

Showing the first eight; more decompositions exist.
