Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446174, here are decompositions:

7 + 31446167 = 31446174
41 + 31446133 = 31446174
43 + 31446131 = 31446174
73 + 31446101 = 31446174
107 + 31446067 = 31446174
113 + 31446061 = 31446174
163 + 31446011 = 31446174
191 + 31445983 = 31446174

Showing the first eight; more decompositions exist.
