Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622722, here are decompositions:

193 + 8622529 = 8622722
211 + 8622511 = 8622722
223 + 8622499 = 8622722
331 + 8622391 = 8622722
349 + 8622373 = 8622722
379 + 8622343 = 8622722
421 + 8622301 = 8622722
499 + 8622223 = 8622722

Showing the first eight; more decompositions exist.
