Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541792, here are decompositions:

31 + 31541761 = 31541792
181 + 31541611 = 31541792
211 + 31541581 = 31541792
223 + 31541569 = 31541792
229 + 31541563 = 31541792
283 + 31541509 = 31541792
433 + 31541359 = 31541792
523 + 31541269 = 31541792

Showing the first eight; more decompositions exist.
