Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461066, here are decompositions:

17 + 31461049 = 31461066
19 + 31461047 = 31461066
29 + 31461037 = 31461066
53 + 31461013 = 31461066
59 + 31461007 = 31461066
89 + 31460977 = 31461066
137 + 31460929 = 31461066
139 + 31460927 = 31461066

Showing the first eight; more decompositions exist.
