Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541260, here are decompositions:

17 + 31541243 = 31541260
131 + 31541129 = 31541260
239 + 31541021 = 31541260
269 + 31540991 = 31541260
281 + 31540979 = 31541260
389 + 31540871 = 31541260
617 + 31540643 = 31541260
761 + 31540499 = 31541260

Showing the first eight; more decompositions exist.
