Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646742, here are decompositions:

23 + 8646719 = 8646742
59 + 8646683 = 8646742
239 + 8646503 = 8646742
263 + 8646479 = 8646742
353 + 8646389 = 8646742
443 + 8646299 = 8646742
449 + 8646293 = 8646742
509 + 8646233 = 8646742

Showing the first eight; more decompositions exist.
