Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542812, here are decompositions:

29 + 542783 = 542812
41 + 542771 = 542812
89 + 542723 = 542812
233 + 542579 = 542812
293 + 542519 = 542812
593 + 542219 = 542812
659 + 542153 = 542812
701 + 542111 = 542812

Showing the first eight; more decompositions exist.
