Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731136, here are decompositions:

67 + 8731069 = 8731136
97 + 8731039 = 8731136
109 + 8731027 = 8731136
223 + 8730913 = 8731136
277 + 8730859 = 8731136
439 + 8730697 = 8731136
487 + 8730649 = 8731136
577 + 8730559 = 8731136

Showing the first eight; more decompositions exist.
