Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731190, here are decompositions:

3 + 8731187 = 8731190
37 + 8731153 = 8731190
79 + 8731111 = 8731190
151 + 8731039 = 8731190
163 + 8731027 = 8731190
241 + 8730949 = 8731190
271 + 8730919 = 8731190
277 + 8730913 = 8731190

Showing the first eight; more decompositions exist.
