Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643502, here are decompositions:

59 + 8643443 = 8643502
293 + 8643209 = 8643502
353 + 8643149 = 8643502
359 + 8643143 = 8643502
419 + 8643083 = 8643502
443 + 8643059 = 8643502
449 + 8643053 = 8643502
479 + 8643023 = 8643502

Showing the first eight; more decompositions exist.
