Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747942, here are decompositions:

13 + 8747929 = 8747942
79 + 8747863 = 8747942
139 + 8747803 = 8747942
199 + 8747743 = 8747942
241 + 8747701 = 8747942
523 + 8747419 = 8747942
613 + 8747329 = 8747942
691 + 8747251 = 8747942

Showing the first eight; more decompositions exist.
