Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749524, here are decompositions:

67 + 8749457 = 8749524
73 + 8749451 = 8749524
101 + 8749423 = 8749524
103 + 8749421 = 8749524
107 + 8749417 = 8749524
167 + 8749357 = 8749524
181 + 8749343 = 8749524
193 + 8749331 = 8749524

Showing the first eight; more decompositions exist.
