Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449318, here are decompositions:

29 + 31449289 = 31449318
31 + 31449287 = 31449318
59 + 31449259 = 31449318
71 + 31449247 = 31449318
127 + 31449191 = 31449318
139 + 31449179 = 31449318
191 + 31449127 = 31449318
281 + 31449037 = 31449318

Showing the first eight; more decompositions exist.
