Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724622, here are decompositions:

3 + 8724619 = 8724622
251 + 8724371 = 8724622
293 + 8724329 = 8724622
311 + 8724311 = 8724622
353 + 8724269 = 8724622
359 + 8724263 = 8724622
461 + 8724161 = 8724622
479 + 8724143 = 8724622

Showing the first eight; more decompositions exist.
