Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446150, here are decompositions:

17 + 31446133 = 31446150
19 + 31446131 = 31446150
53 + 31446097 = 31446150
83 + 31446067 = 31446150
89 + 31446061 = 31446150
97 + 31446053 = 31446150
139 + 31446011 = 31446150
167 + 31445983 = 31446150

Showing the first eight; more decompositions exist.
