Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541634, here are decompositions:

23 + 31541611 = 31541634
37 + 31541597 = 31541634
43 + 31541591 = 31541634
53 + 31541581 = 31541634
71 + 31541563 = 31541634
107 + 31541527 = 31541634
127 + 31541507 = 31541634
151 + 31541483 = 31541634

Showing the first eight; more decompositions exist.
