Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701742, here are decompositions:

13 + 8701729 = 8701742
19 + 8701723 = 8701742
211 + 8701531 = 8701742
223 + 8701519 = 8701742
421 + 8701321 = 8701742
433 + 8701309 = 8701742
463 + 8701279 = 8701742
499 + 8701243 = 8701742

Showing the first eight; more decompositions exist.
