Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454002, here are decompositions:

5 + 31453997 = 31454002
11 + 31453991 = 31454002
59 + 31453943 = 31454002
71 + 31453931 = 31454002
179 + 31453823 = 31454002
269 + 31453733 = 31454002
431 + 31453571 = 31454002
479 + 31453523 = 31454002

Showing the first eight; more decompositions exist.
