Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731718, here are decompositions:

7 + 8731711 = 8731718
19 + 8731699 = 8731718
31 + 8731687 = 8731718
109 + 8731609 = 8731718
139 + 8731579 = 8731718
241 + 8731477 = 8731718
271 + 8731447 = 8731718
337 + 8731381 = 8731718

Showing the first eight; more decompositions exist.
