Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453546, here are decompositions:

17 + 31453529 = 31453546
23 + 31453523 = 31453546
83 + 31453463 = 31453546
263 + 31453283 = 31453546
353 + 31453193 = 31453546
389 + 31453157 = 31453546
569 + 31452977 = 31453546
743 + 31452803 = 31453546

Showing the first eight; more decompositions exist.
