Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154930, here are decompositions:

3 + 154927 = 154930
47 + 154883 = 154930
53 + 154877 = 154930
59 + 154871 = 154930
89 + 154841 = 154930
107 + 154823 = 154930
131 + 154799 = 154930
197 + 154733 = 154930

Showing the first eight; more decompositions exist.
