Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446162, here are decompositions:

29 + 31446133 = 31446162
31 + 31446131 = 31446162
61 + 31446101 = 31446162
101 + 31446061 = 31446162
109 + 31446053 = 31446162
131 + 31446031 = 31446162
151 + 31446011 = 31446162
179 + 31445983 = 31446162

Showing the first eight; more decompositions exist.
