Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731760, here are decompositions:

3 + 8731757 = 8731760
61 + 8731699 = 8731760
73 + 8731687 = 8731760
151 + 8731609 = 8731760
181 + 8731579 = 8731760
229 + 8731531 = 8731760
283 + 8731477 = 8731760
313 + 8731447 = 8731760

Showing the first eight; more decompositions exist.
