Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471088, here are decompositions:

37 + 31471051 = 31471088
97 + 31470991 = 31471088
199 + 31470889 = 31471088
241 + 31470847 = 31471088
307 + 31470781 = 31471088
367 + 31470721 = 31471088
379 + 31470709 = 31471088
541 + 31470547 = 31471088

Showing the first eight; more decompositions exist.
