Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449182, here are decompositions:

3 + 31449179 = 31449182
19 + 31449163 = 31449182
139 + 31449043 = 31449182
283 + 31448899 = 31449182
379 + 31448803 = 31449182
463 + 31448719 = 31449182
601 + 31448581 = 31449182
631 + 31448551 = 31449182

Showing the first eight; more decompositions exist.
