Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461050, here are decompositions:

3 + 31461047 = 31461050
13 + 31461037 = 31461050
37 + 31461013 = 31461050
43 + 31461007 = 31461050
73 + 31460977 = 31461050
79 + 31460971 = 31461050
199 + 31460851 = 31461050
211 + 31460839 = 31461050

Showing the first eight; more decompositions exist.
