Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453264, here are decompositions:

23 + 31453241 = 31453264
71 + 31453193 = 31453264
83 + 31453181 = 31453264
107 + 31453157 = 31453264
131 + 31453133 = 31453264
461 + 31452803 = 31453264
587 + 31452677 = 31453264
641 + 31452623 = 31453264

Showing the first eight; more decompositions exist.
