Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500890, here are decompositions:

3 + 500887 = 500890
17 + 500873 = 500890
29 + 500861 = 500890
59 + 500831 = 500890
83 + 500807 = 500890
113 + 500777 = 500890
149 + 500741 = 500890
167 + 500723 = 500890

Showing the first eight; more decompositions exist.
