Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539812, here are decompositions:

29 + 539783 = 539812
83 + 539729 = 539812
89 + 539723 = 539812
101 + 539711 = 539812
149 + 539663 = 539812
173 + 539639 = 539812
179 + 539633 = 539812
191 + 539621 = 539812

Showing the first eight; more decompositions exist.
