Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151854, here are decompositions:

5 + 151849 = 151854
7 + 151847 = 151854
13 + 151841 = 151854
37 + 151817 = 151854
41 + 151813 = 151854
67 + 151787 = 151854
71 + 151783 = 151854
83 + 151771 = 151854

Showing the first eight; more decompositions exist.
