Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151926, here are decompositions:

17 + 151909 = 151926
23 + 151903 = 151926
29 + 151897 = 151926
43 + 151883 = 151926
79 + 151847 = 151926
109 + 151817 = 151926
113 + 151813 = 151926
127 + 151799 = 151926

Showing the first eight; more decompositions exist.
