Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449348, here are decompositions:

59 + 31449289 = 31449348
61 + 31449287 = 31449348
89 + 31449259 = 31449348
101 + 31449247 = 31449348
107 + 31449241 = 31449348
157 + 31449191 = 31449348
277 + 31449071 = 31449348
311 + 31449037 = 31449348

Showing the first eight; more decompositions exist.
