Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161054, here are decompositions:

7 + 161047 = 161054
37 + 161017 = 161054
73 + 160981 = 161054
151 + 160903 = 161054
193 + 160861 = 161054
241 + 160813 = 161054
331 + 160723 = 161054
367 + 160687 = 161054

Showing the first eight; more decompositions exist.
