Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151850, here are decompositions:

3 + 151847 = 151850
37 + 151813 = 151850
67 + 151783 = 151850
79 + 151771 = 151850
157 + 151693 = 151850
163 + 151687 = 151850
199 + 151651 = 151850
241 + 151609 = 151850

Showing the first eight; more decompositions exist.
