Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449204, here are decompositions:

13 + 31449191 = 31449204
41 + 31449163 = 31449204
151 + 31449053 = 31449204
167 + 31449037 = 31449204
307 + 31448897 = 31449204
313 + 31448891 = 31449204
383 + 31448821 = 31449204
401 + 31448803 = 31449204

Showing the first eight; more decompositions exist.
