Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449202, here are decompositions:

11 + 31449191 = 31449202
23 + 31449179 = 31449202
131 + 31449071 = 31449202
149 + 31449053 = 31449202
173 + 31449029 = 31449202
293 + 31448909 = 31449202
311 + 31448891 = 31449202
461 + 31448741 = 31449202

Showing the first eight; more decompositions exist.
