Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449976, here are decompositions:

53 + 31449923 = 31449976
347 + 31449629 = 31449976
419 + 31449557 = 31449976
449 + 31449527 = 31449976
599 + 31449377 = 31449976
617 + 31449359 = 31449976
653 + 31449323 = 31449976
743 + 31449233 = 31449976

Showing the first eight; more decompositions exist.
