Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491616, here are decompositions:

5 + 491611 = 491616
23 + 491593 = 491616
79 + 491537 = 491616
89 + 491527 = 491616
113 + 491503 = 491616
127 + 491489 = 491616
193 + 491423 = 491616
199 + 491417 = 491616

Showing the first eight; more decompositions exist.
