Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521862, here are decompositions:

31 + 521831 = 521862
43 + 521819 = 521862
53 + 521809 = 521862
71 + 521791 = 521862
73 + 521789 = 521862
109 + 521753 = 521862
113 + 521749 = 521862
139 + 521723 = 521862

Showing the first eight; more decompositions exist.
