Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449222, here are decompositions:

31 + 31449191 = 31449222
43 + 31449179 = 31449222
59 + 31449163 = 31449222
139 + 31449083 = 31449222
151 + 31449071 = 31449222
179 + 31449043 = 31449222
193 + 31449029 = 31449222
313 + 31448909 = 31449222

Showing the first eight; more decompositions exist.
