Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731488, here are decompositions:

11 + 8731477 = 8731488
41 + 8731447 = 8731488
61 + 8731427 = 8731488
71 + 8731417 = 8731488
107 + 8731381 = 8731488
149 + 8731339 = 8731488
167 + 8731321 = 8731488
179 + 8731309 = 8731488

Showing the first eight; more decompositions exist.
