Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151884, here are decompositions:

13 + 151871 = 151884
37 + 151847 = 151884
43 + 151841 = 151884
67 + 151817 = 151884
71 + 151813 = 151884
97 + 151787 = 151884
101 + 151783 = 151884
113 + 151771 = 151884

Showing the first eight; more decompositions exist.
