Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186730, here are decompositions:

3 + 186727 = 186730
23 + 186707 = 186730
29 + 186701 = 186730
41 + 186689 = 186730
59 + 186671 = 186730
83 + 186647 = 186730
101 + 186629 = 186730
149 + 186581 = 186730

Showing the first eight; more decompositions exist.
