Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449396, here are decompositions:

19 + 31449377 = 31449396
23 + 31449373 = 31449396
37 + 31449359 = 31449396
73 + 31449323 = 31449396
107 + 31449289 = 31449396
109 + 31449287 = 31449396
137 + 31449259 = 31449396
149 + 31449247 = 31449396

Showing the first eight; more decompositions exist.
