Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463570, here are decompositions:

37 + 31463533 = 31463570
43 + 31463527 = 31463570
163 + 31463407 = 31463570
181 + 31463389 = 31463570
241 + 31463329 = 31463570
367 + 31463203 = 31463570
373 + 31463197 = 31463570
409 + 31463161 = 31463570

Showing the first eight; more decompositions exist.
