Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541624, here are decompositions:

13 + 31541611 = 31541624
43 + 31541581 = 31541624
61 + 31541563 = 31541624
67 + 31541557 = 31541624
97 + 31541527 = 31541624
157 + 31541467 = 31541624
223 + 31541401 = 31541624
277 + 31541347 = 31541624

Showing the first eight; more decompositions exist.
