Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151908, here are decompositions:

5 + 151903 = 151908
7 + 151901 = 151908
11 + 151897 = 151908
37 + 151871 = 151908
59 + 151849 = 151908
61 + 151847 = 151908
67 + 151841 = 151908
109 + 151799 = 151908

Showing the first eight; more decompositions exist.
