Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536448, here are decompositions:

89 + 31536359 = 31536448
101 + 31536347 = 31536448
347 + 31536101 = 31536448
431 + 31536017 = 31536448
467 + 31535981 = 31536448
509 + 31535939 = 31536448
569 + 31535879 = 31536448
617 + 31535831 = 31536448

Showing the first eight; more decompositions exist.
