Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726742, here are decompositions:

5 + 8726737 = 8726742
19 + 8726723 = 8726742
29 + 8726713 = 8726742
43 + 8726699 = 8726742
71 + 8726671 = 8726742
109 + 8726633 = 8726742
131 + 8726611 = 8726742
173 + 8726569 = 8726742

Showing the first eight; more decompositions exist.
