Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731248, here are decompositions:

17 + 8731231 = 8731248
37 + 8731211 = 8731248
47 + 8731201 = 8731248
61 + 8731187 = 8731248
107 + 8731141 = 8731248
109 + 8731139 = 8731248
137 + 8731111 = 8731248
139 + 8731109 = 8731248

Showing the first eight; more decompositions exist.
