Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446962, here are decompositions:

13 + 31446949 = 31446962
103 + 31446859 = 31446962
109 + 31446853 = 31446962
193 + 31446769 = 31446962
223 + 31446739 = 31446962
409 + 31446553 = 31446962
523 + 31446439 = 31446962
601 + 31446361 = 31446962

Showing the first eight; more decompositions exist.
