Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449468, here are decompositions:

5 + 31449463 = 31449468
19 + 31449449 = 31449468
47 + 31449421 = 31449468
59 + 31449409 = 31449468
67 + 31449401 = 31449468
107 + 31449361 = 31449468
109 + 31449359 = 31449468
179 + 31449289 = 31449468

Showing the first eight; more decompositions exist.
