Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461044, here are decompositions:

7 + 31461037 = 31461044
31 + 31461013 = 31461044
37 + 31461007 = 31461044
67 + 31460977 = 31461044
73 + 31460971 = 31461044
127 + 31460917 = 31461044
193 + 31460851 = 31461044
211 + 31460833 = 31461044

Showing the first eight; more decompositions exist.
