Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544546, here are decompositions:

3 + 31544543 = 31544546
13 + 31544533 = 31544546
37 + 31544509 = 31544546
199 + 31544347 = 31544546
223 + 31544323 = 31544546
367 + 31544179 = 31544546
379 + 31544167 = 31544546
457 + 31544089 = 31544546

Showing the first eight; more decompositions exist.
