Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453462, here are decompositions:

41 + 31453421 = 31453462
71 + 31453391 = 31453462
101 + 31453361 = 31453462
179 + 31453283 = 31453462
269 + 31453193 = 31453462
281 + 31453181 = 31453462
659 + 31452803 = 31453462
743 + 31452719 = 31453462

Showing the first eight; more decompositions exist.
