Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541594, here are decompositions:

3 + 31541591 = 31541594
13 + 31541581 = 31541594
31 + 31541563 = 31541594
37 + 31541557 = 31541594
67 + 31541527 = 31541594
127 + 31541467 = 31541594
157 + 31541437 = 31541594
193 + 31541401 = 31541594

Showing the first eight; more decompositions exist.
