Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643412, here are decompositions:

3 + 8643409 = 8643412
53 + 8643359 = 8643412
131 + 8643281 = 8643412
263 + 8643149 = 8643412
269 + 8643143 = 8643412
353 + 8643059 = 8643412
359 + 8643053 = 8643412
389 + 8643023 = 8643412

Showing the first eight; more decompositions exist.
