Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747458, here are decompositions:

17 + 8747441 = 8747458
131 + 8747327 = 8747458
197 + 8747261 = 8747458
347 + 8747111 = 8747458
479 + 8746979 = 8747458
491 + 8746967 = 8747458
509 + 8746949 = 8747458
521 + 8746937 = 8747458

Showing the first eight; more decompositions exist.
