Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541588, here are decompositions:

7 + 31541581 = 31541588
19 + 31541569 = 31541588
31 + 31541557 = 31541588
61 + 31541527 = 31541588
79 + 31541509 = 31541588
139 + 31541449 = 31541588
151 + 31541437 = 31541588
229 + 31541359 = 31541588

Showing the first eight; more decompositions exist.
