Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677442, here are decompositions:

43 + 8677399 = 8677442
181 + 8677261 = 8677442
271 + 8677171 = 8677442
643 + 8676799 = 8677442
661 + 8676781 = 8677442
673 + 8676769 = 8677442
691 + 8676751 = 8677442
751 + 8676691 = 8677442

Showing the first eight; more decompositions exist.
