Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731318, here are decompositions:

5 + 8731313 = 8731318
17 + 8731301 = 8731318
41 + 8731277 = 8731318
107 + 8731211 = 8731318
131 + 8731187 = 8731318
179 + 8731139 = 8731318
389 + 8730929 = 8731318
461 + 8730857 = 8731318

Showing the first eight; more decompositions exist.
