Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454362, here are decompositions:

11 + 31454351 = 31454362
41 + 31454321 = 31454362
113 + 31454249 = 31454362
239 + 31454123 = 31454362
281 + 31454081 = 31454362
419 + 31453943 = 31454362
431 + 31453931 = 31454362
479 + 31453883 = 31454362

Showing the first eight; more decompositions exist.
