Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747632, here are decompositions:

29 + 8747603 = 8747632
53 + 8747579 = 8747632
59 + 8747573 = 8747632
71 + 8747561 = 8747632
149 + 8747483 = 8747632
191 + 8747441 = 8747632
251 + 8747381 = 8747632
359 + 8747273 = 8747632

Showing the first eight; more decompositions exist.
