Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539722, here are decompositions:

11 + 539711 = 539722
59 + 539663 = 539722
83 + 539639 = 539722
89 + 539633 = 539722
101 + 539621 = 539722
149 + 539573 = 539722
383 + 539339 = 539722
401 + 539321 = 539722

Showing the first eight; more decompositions exist.
