Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543614, here are decompositions:

43 + 31543571 = 31543614
71 + 31543543 = 31543614
83 + 31543531 = 31543614
163 + 31543451 = 31543614
283 + 31543331 = 31543614
313 + 31543301 = 31543614
383 + 31543231 = 31543614
397 + 31543217 = 31543614

Showing the first eight; more decompositions exist.
