Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541586, here are decompositions:

5 + 31541581 = 31541586
17 + 31541569 = 31541586
23 + 31541563 = 31541586
29 + 31541557 = 31541586
59 + 31541527 = 31541586
79 + 31541507 = 31541586
103 + 31541483 = 31541586
137 + 31541449 = 31541586

Showing the first eight; more decompositions exist.
