Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757042, here are decompositions:

5 + 8757037 = 8757042
13 + 8757029 = 8757042
23 + 8757019 = 8757042
29 + 8757013 = 8757042
43 + 8756999 = 8757042
59 + 8756983 = 8757042
61 + 8756981 = 8757042
71 + 8756971 = 8757042

Showing the first eight; more decompositions exist.
