Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461850, here are decompositions:

59 + 31461791 = 31461850
71 + 31461779 = 31461850
89 + 31461761 = 31461850
107 + 31461743 = 31461850
113 + 31461737 = 31461850
197 + 31461653 = 31461850
281 + 31461569 = 31461850
293 + 31461557 = 31461850

Showing the first eight; more decompositions exist.
