Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643746, here are decompositions:

73 + 8643673 = 8643746
127 + 8643619 = 8643746
157 + 8643589 = 8643746
313 + 8643433 = 8643746
337 + 8643409 = 8643746
379 + 8643367 = 8643746
409 + 8643337 = 8643746
439 + 8643307 = 8643746

Showing the first eight; more decompositions exist.
