Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724670, here are decompositions:

29 + 8724641 = 8724670
173 + 8724497 = 8724670
191 + 8724479 = 8724670
233 + 8724437 = 8724670
293 + 8724377 = 8724670
347 + 8724323 = 8724670
359 + 8724311 = 8724670
401 + 8724269 = 8724670

Showing the first eight; more decompositions exist.
