Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449662, here are decompositions:

43 + 31449619 = 31449662
73 + 31449589 = 31449662
109 + 31449553 = 31449662
163 + 31449499 = 31449662
199 + 31449463 = 31449662
241 + 31449421 = 31449662
373 + 31449289 = 31449662
421 + 31449241 = 31449662

Showing the first eight; more decompositions exist.
