Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662642, here are decompositions:

59 + 8662583 = 8662642
89 + 8662553 = 8662642
101 + 8662541 = 8662642
293 + 8662349 = 8662642
383 + 8662259 = 8662642
419 + 8662223 = 8662642
491 + 8662151 = 8662642
509 + 8662133 = 8662642

Showing the first eight; more decompositions exist.
