Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449754, here are decompositions:

3 + 31449751 = 31449754
53 + 31449701 = 31449754
107 + 31449647 = 31449754
173 + 31449581 = 31449754
197 + 31449557 = 31449754
227 + 31449527 = 31449754
353 + 31449401 = 31449754
431 + 31449323 = 31449754

Showing the first eight; more decompositions exist.
