Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749372, here are decompositions:

29 + 8749343 = 8749372
41 + 8749331 = 8749372
173 + 8749199 = 8749372
239 + 8749133 = 8749372
251 + 8749121 = 8749372
353 + 8749019 = 8749372
383 + 8748989 = 8749372
419 + 8748953 = 8749372

Showing the first eight; more decompositions exist.
