Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747236, here are decompositions:

23 + 8747213 = 8747236
257 + 8746979 = 8747236
269 + 8746967 = 8747236
317 + 8746919 = 8747236
389 + 8746847 = 8747236
479 + 8746757 = 8747236
503 + 8746733 = 8747236
557 + 8746679 = 8747236

Showing the first eight; more decompositions exist.
