Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449982, here are decompositions:

59 + 31449923 = 31449982
191 + 31449791 = 31449982
281 + 31449701 = 31449982
293 + 31449689 = 31449982
353 + 31449629 = 31449982
401 + 31449581 = 31449982
503 + 31449479 = 31449982
659 + 31449323 = 31449982

Showing the first eight; more decompositions exist.
