Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611070, here are decompositions:

3 + 31611067 = 31611070
41 + 31611029 = 31611070
47 + 31611023 = 31611070
53 + 31611017 = 31611070
59 + 31611011 = 31611070
347 + 31610723 = 31611070
431 + 31610639 = 31611070
509 + 31610561 = 31611070

Showing the first eight; more decompositions exist.
