Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122690, here are decompositions:

37 + 122653 = 122690
79 + 122611 = 122690
157 + 122533 = 122690
163 + 122527 = 122690
181 + 122509 = 122690
193 + 122497 = 122690
241 + 122449 = 122690
367 + 122323 = 122690

Showing the first eight; more decompositions exist.
