Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749518, here are decompositions:

61 + 8749457 = 8749518
67 + 8749451 = 8749518
79 + 8749439 = 8749518
97 + 8749421 = 8749518
101 + 8749417 = 8749518
181 + 8749337 = 8749518
311 + 8749207 = 8749518
367 + 8749151 = 8749518

Showing the first eight; more decompositions exist.
