Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620136, here are decompositions:

3 + 8620133 = 8620136
67 + 8620069 = 8620136
73 + 8620063 = 8620136
139 + 8619997 = 8620136
193 + 8619943 = 8620136
199 + 8619937 = 8620136
277 + 8619859 = 8620136
487 + 8619649 = 8620136

Showing the first eight; more decompositions exist.
