Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670290, here are decompositions:

163 + 8670127 = 8670290
283 + 8670007 = 8670290
367 + 8669923 = 8670290
379 + 8669911 = 8670290
397 + 8669893 = 8670290
523 + 8669767 = 8670290
619 + 8669671 = 8670290
661 + 8669629 = 8670290

Showing the first eight; more decompositions exist.
