Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732340, here are decompositions:

31 + 8732309 = 8732340
41 + 8732299 = 8732340
79 + 8732261 = 8732340
83 + 8732257 = 8732340
101 + 8732239 = 8732340
131 + 8732209 = 8732340
139 + 8732201 = 8732340
151 + 8732189 = 8732340

Showing the first eight; more decompositions exist.
