Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454332, here are decompositions:

11 + 31454321 = 31454332
83 + 31454249 = 31454332
113 + 31454219 = 31454332
131 + 31454201 = 31454332
251 + 31454081 = 31454332
389 + 31453943 = 31454332
401 + 31453931 = 31454332
449 + 31453883 = 31454332

Showing the first eight; more decompositions exist.
