Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731766, here are decompositions:

3 + 8731763 = 8731766
67 + 8731699 = 8731766
79 + 8731687 = 8731766
139 + 8731627 = 8731766
157 + 8731609 = 8731766
349 + 8731417 = 8731766
397 + 8731369 = 8731766
457 + 8731309 = 8731766

Showing the first eight; more decompositions exist.
