Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541652, here are decompositions:

19 + 31541633 = 31541652
41 + 31541611 = 31541652
61 + 31541591 = 31541652
71 + 31541581 = 31541652
83 + 31541569 = 31541652
89 + 31541563 = 31541652
223 + 31541429 = 31541652
251 + 31541401 = 31541652

Showing the first eight; more decompositions exist.
