Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449792, here are decompositions:

41 + 31449751 = 31449792
53 + 31449739 = 31449792
103 + 31449689 = 31449792
113 + 31449679 = 31449792
163 + 31449629 = 31449792
173 + 31449619 = 31449792
181 + 31449611 = 31449792
211 + 31449581 = 31449792

Showing the first eight; more decompositions exist.
