Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449196, here are decompositions:

5 + 31449191 = 31449196
17 + 31449179 = 31449196
113 + 31449083 = 31449196
167 + 31449029 = 31449196
179 + 31449017 = 31449196
293 + 31448903 = 31449196
479 + 31448717 = 31449196
503 + 31448693 = 31449196

Showing the first eight; more decompositions exist.
