Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541670, here are decompositions:

11 + 31541659 = 31541670
19 + 31541651 = 31541670
37 + 31541633 = 31541670
59 + 31541611 = 31541670
73 + 31541597 = 31541670
79 + 31541591 = 31541670
89 + 31541581 = 31541670
101 + 31541569 = 31541670

Showing the first eight; more decompositions exist.
