Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449094, here are decompositions:

11 + 31449083 = 31449094
23 + 31449071 = 31449094
41 + 31449053 = 31449094
107 + 31448987 = 31449094
191 + 31448903 = 31449094
197 + 31448897 = 31449094
353 + 31448741 = 31449094
401 + 31448693 = 31449094

Showing the first eight; more decompositions exist.
