Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749530, here are decompositions:

61 + 8749469 = 8749530
73 + 8749457 = 8749530
79 + 8749451 = 8749530
107 + 8749423 = 8749530
109 + 8749421 = 8749530
113 + 8749417 = 8749530
173 + 8749357 = 8749530
193 + 8749337 = 8749530

Showing the first eight; more decompositions exist.
