Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661674, here are decompositions:

31 + 8661643 = 8661674
97 + 8661577 = 8661674
103 + 8661571 = 8661674
421 + 8661253 = 8661674
433 + 8661241 = 8661674
457 + 8661217 = 8661674
613 + 8661061 = 8661674
631 + 8661043 = 8661674

Showing the first eight; more decompositions exist.
