Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151944, here are decompositions:

5 + 151939 = 151944
7 + 151937 = 151944
41 + 151903 = 151944
43 + 151901 = 151944
47 + 151897 = 151944
61 + 151883 = 151944
73 + 151871 = 151944
97 + 151847 = 151944

Showing the first eight; more decompositions exist.
