Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493614, here are decompositions:

3 + 31493611 = 31493614
41 + 31493573 = 31493614
101 + 31493513 = 31493614
137 + 31493477 = 31493614
167 + 31493447 = 31493614
293 + 31493321 = 31493614
443 + 31493171 = 31493614
461 + 31493153 = 31493614

Showing the first eight; more decompositions exist.
