Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471052, here are decompositions:

61 + 31470991 = 31471052
139 + 31470913 = 31471052
163 + 31470889 = 31471052
199 + 31470853 = 31471052
229 + 31470823 = 31471052
271 + 31470781 = 31471052
331 + 31470721 = 31471052
433 + 31470619 = 31471052

Showing the first eight; more decompositions exist.
