Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494464, here are decompositions:

37 + 31494427 = 31494464
163 + 31494301 = 31494464
223 + 31494241 = 31494464
307 + 31494157 = 31494464
367 + 31494097 = 31494464
373 + 31494091 = 31494464
523 + 31493941 = 31494464
607 + 31493857 = 31494464

Showing the first eight; more decompositions exist.
