Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463998, here are decompositions:

89 + 31463909 = 31463998
101 + 31463897 = 31463998
107 + 31463891 = 31463998
149 + 31463849 = 31463998
191 + 31463807 = 31463998
239 + 31463759 = 31463998
281 + 31463717 = 31463998
317 + 31463681 = 31463998

Showing the first eight; more decompositions exist.
