Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731274, here are decompositions:

43 + 8731231 = 8731274
61 + 8731213 = 8731274
73 + 8731201 = 8731274
163 + 8731111 = 8731274
373 + 8730901 = 8731274
577 + 8730697 = 8731274
613 + 8730661 = 8731274
691 + 8730583 = 8731274

Showing the first eight; more decompositions exist.
