Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661974, here are decompositions:

31 + 8661943 = 8661974
73 + 8661901 = 8661974
103 + 8661871 = 8661974
241 + 8661733 = 8661974
271 + 8661703 = 8661974
331 + 8661643 = 8661974
397 + 8661577 = 8661974
421 + 8661553 = 8661974

Showing the first eight; more decompositions exist.
