Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446932, here are decompositions:

61 + 31446871 = 31446932
73 + 31446859 = 31446932
79 + 31446853 = 31446932
163 + 31446769 = 31446932
193 + 31446739 = 31446932
379 + 31446553 = 31446932
571 + 31446361 = 31446932
691 + 31446241 = 31446932

Showing the first eight; more decompositions exist.
