Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000642, here are decompositions:

3 + 1000639 = 1000642
23 + 1000619 = 1000642
53 + 1000589 = 1000642
101 + 1000541 = 1000642
233 + 1000409 = 1000642
239 + 1000403 = 1000642
353 + 1000289 = 1000642
389 + 1000253 = 1000642

Showing the first eight; more decompositions exist.
