Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461982, here are decompositions:

3 + 31461979 = 31461982
5 + 31461977 = 31461982
59 + 31461923 = 31461982
89 + 31461893 = 31461982
131 + 31461851 = 31461982
191 + 31461791 = 31461982
239 + 31461743 = 31461982
449 + 31461533 = 31461982

Showing the first eight; more decompositions exist.
