Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731070, here are decompositions:

31 + 8731039 = 8731070
43 + 8731027 = 8731070
151 + 8730919 = 8731070
157 + 8730913 = 8731070
181 + 8730889 = 8731070
211 + 8730859 = 8731070
223 + 8730847 = 8731070
277 + 8730793 = 8731070

Showing the first eight; more decompositions exist.
