Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624938, here are decompositions:

17 + 8624921 = 8624938
131 + 8624807 = 8624938
167 + 8624771 = 8624938
269 + 8624669 = 8624938
317 + 8624621 = 8624938
431 + 8624507 = 8624938
461 + 8624477 = 8624938
479 + 8624459 = 8624938

Showing the first eight; more decompositions exist.
