Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145854, here are decompositions:

31 + 145823 = 145854
47 + 145807 = 145854
83 + 145771 = 145854
97 + 145757 = 145854
101 + 145753 = 145854
131 + 145723 = 145854
151 + 145703 = 145854
167 + 145687 = 145854

Showing the first eight; more decompositions exist.
