Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449448, here are decompositions:

47 + 31449401 = 31449448
71 + 31449377 = 31449448
89 + 31449359 = 31449448
257 + 31449191 = 31449448
269 + 31449179 = 31449448
419 + 31449029 = 31449448
431 + 31449017 = 31449448
461 + 31448987 = 31449448

Showing the first eight; more decompositions exist.
