Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492730, here are decompositions:

11 + 492719 = 492730
23 + 492707 = 492730
59 + 492671 = 492730
71 + 492659 = 492730
83 + 492647 = 492730
89 + 492641 = 492730
101 + 492629 = 492730
113 + 492617 = 492730

Showing the first eight; more decompositions exist.
