Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542668, here are decompositions:

89 + 542579 = 542668
101 + 542567 = 542668
131 + 542537 = 542668
149 + 542519 = 542668
179 + 542489 = 542668
227 + 542441 = 542668
431 + 542237 = 542668
449 + 542219 = 542668

Showing the first eight; more decompositions exist.
