Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731016, here are decompositions:

67 + 8730949 = 8731016
97 + 8730919 = 8731016
103 + 8730913 = 8731016
127 + 8730889 = 8731016
157 + 8730859 = 8731016
223 + 8730793 = 8731016
367 + 8730649 = 8731016
397 + 8730619 = 8731016

Showing the first eight; more decompositions exist.
