Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757742, here are decompositions:

23 + 8757719 = 8757742
29 + 8757713 = 8757742
41 + 8757701 = 8757742
83 + 8757659 = 8757742
173 + 8757569 = 8757742
179 + 8757563 = 8757742
269 + 8757473 = 8757742
353 + 8757389 = 8757742

Showing the first eight; more decompositions exist.
