Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446204, here are decompositions:

37 + 31446167 = 31446204
71 + 31446133 = 31446204
73 + 31446131 = 31446204
103 + 31446101 = 31446204
107 + 31446097 = 31446204
137 + 31446067 = 31446204
151 + 31446053 = 31446204
173 + 31446031 = 31446204

Showing the first eight; more decompositions exist.
