Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461146, here are decompositions:

19 + 31461127 = 31461146
97 + 31461049 = 31461146
109 + 31461037 = 31461146
139 + 31461007 = 31461146
229 + 31460917 = 31461146
307 + 31460839 = 31461146
313 + 31460833 = 31461146
337 + 31460809 = 31461146

Showing the first eight; more decompositions exist.
