Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454554, here are decompositions:

41 + 31454513 = 31454554
71 + 31454483 = 31454554
113 + 31454441 = 31454554
233 + 31454321 = 31454554
353 + 31454201 = 31454554
431 + 31454123 = 31454554
557 + 31453997 = 31454554
563 + 31453991 = 31454554

Showing the first eight; more decompositions exist.
