Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731826, here are decompositions:

7 + 8731819 = 8731826
43 + 8731783 = 8731826
127 + 8731699 = 8731826
139 + 8731687 = 8731826
199 + 8731627 = 8731826
349 + 8731477 = 8731826
379 + 8731447 = 8731826
409 + 8731417 = 8731826

Showing the first eight; more decompositions exist.
