Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541008, here are decompositions:

17 + 31540991 = 31541008
29 + 31540979 = 31541008
47 + 31540961 = 31541008
137 + 31540871 = 31541008
281 + 31540727 = 31541008
479 + 31540529 = 31541008
509 + 31540499 = 31541008
797 + 31540211 = 31541008

Showing the first eight; more decompositions exist.
