Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449962, here are decompositions:

31 + 31449931 = 31449962
109 + 31449853 = 31449962
139 + 31449823 = 31449962
211 + 31449751 = 31449962
223 + 31449739 = 31449962
283 + 31449679 = 31449962
373 + 31449589 = 31449962
409 + 31449553 = 31449962

Showing the first eight; more decompositions exist.
