Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726222, here are decompositions:

13 + 8726209 = 8726222
19 + 8726203 = 8726222
79 + 8726143 = 8726222
223 + 8725999 = 8726222
409 + 8725813 = 8726222
523 + 8725699 = 8726222
541 + 8725681 = 8726222
601 + 8725621 = 8726222

Showing the first eight; more decompositions exist.
