Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449192, here are decompositions:

13 + 31449179 = 31449192
29 + 31449163 = 31449192
109 + 31449083 = 31449192
139 + 31449053 = 31449192
149 + 31449043 = 31449192
163 + 31449029 = 31449192
283 + 31448909 = 31449192
293 + 31448899 = 31449192

Showing the first eight; more decompositions exist.
