Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747742, here are decompositions:

5 + 8747737 = 8747742
19 + 8747723 = 8747742
41 + 8747701 = 8747742
53 + 8747689 = 8747742
89 + 8747653 = 8747742
139 + 8747603 = 8747742
163 + 8747579 = 8747742
181 + 8747561 = 8747742

Showing the first eight; more decompositions exist.
