Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542926, here are decompositions:

97 + 31542829 = 31542926
127 + 31542799 = 31542926
139 + 31542787 = 31542926
199 + 31542727 = 31542926
223 + 31542703 = 31542926
229 + 31542697 = 31542926
313 + 31542613 = 31542926
367 + 31542559 = 31542926

Showing the first eight; more decompositions exist.
