Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731160, here are decompositions:

7 + 8731153 = 8731160
19 + 8731141 = 8731160
211 + 8730949 = 8731160
241 + 8730919 = 8731160
271 + 8730889 = 8731160
313 + 8730847 = 8731160
367 + 8730793 = 8731160
379 + 8730781 = 8731160

Showing the first eight; more decompositions exist.
