Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747638, here are decompositions:

59 + 8747579 = 8747638
149 + 8747489 = 8747638
167 + 8747471 = 8747638
197 + 8747441 = 8747638
257 + 8747381 = 8747638
311 + 8747327 = 8747638
467 + 8747171 = 8747638
479 + 8747159 = 8747638

Showing the first eight; more decompositions exist.
