Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445014, here are decompositions:

5 + 31445009 = 31445014
113 + 31444901 = 31445014
137 + 31444877 = 31445014
353 + 31444661 = 31445014
383 + 31444631 = 31445014
467 + 31444547 = 31445014
647 + 31444367 = 31445014
701 + 31444313 = 31445014

Showing the first eight; more decompositions exist.
