Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701942, here are decompositions:

59 + 8701883 = 8701942
71 + 8701871 = 8701942
89 + 8701853 = 8701942
131 + 8701811 = 8701942
233 + 8701709 = 8701942
239 + 8701703 = 8701942
311 + 8701631 = 8701942
383 + 8701559 = 8701942

Showing the first eight; more decompositions exist.
