Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757438, here are decompositions:

29 + 8757409 = 8757438
59 + 8757379 = 8757438
61 + 8757377 = 8757438
97 + 8757341 = 8757438
149 + 8757289 = 8757438
229 + 8757209 = 8757438
251 + 8757187 = 8757438
307 + 8757131 = 8757438

Showing the first eight; more decompositions exist.
