Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541762, here are decompositions:

103 + 31541659 = 31541762
151 + 31541611 = 31541762
181 + 31541581 = 31541762
193 + 31541569 = 31541762
199 + 31541563 = 31541762
313 + 31541449 = 31541762
601 + 31541161 = 31541762
661 + 31541101 = 31541762

Showing the first eight; more decompositions exist.
