Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698490, here are decompositions:

127 + 8698363 = 8698490
193 + 8698297 = 8698490
277 + 8698213 = 8698490
337 + 8698153 = 8698490
379 + 8698111 = 8698490
397 + 8698093 = 8698490
523 + 8697967 = 8698490
547 + 8697943 = 8698490

Showing the first eight; more decompositions exist.
