Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449292, here are decompositions:

3 + 31449289 = 31449292
5 + 31449287 = 31449292
29 + 31449263 = 31449292
59 + 31449233 = 31449292
101 + 31449191 = 31449292
113 + 31449179 = 31449292
239 + 31449053 = 31449292
263 + 31449029 = 31449292

Showing the first eight; more decompositions exist.
