Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751724, here are decompositions:

53 + 8751671 = 8751724
131 + 8751593 = 8751724
167 + 8751557 = 8751724
197 + 8751527 = 8751724
257 + 8751467 = 8751724
263 + 8751461 = 8751724
353 + 8751371 = 8751724
383 + 8751341 = 8751724

Showing the first eight; more decompositions exist.
