Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543654, here are decompositions:

11 + 31543643 = 31543654
83 + 31543571 = 31543654
173 + 31543481 = 31543654
257 + 31543397 = 31543654
293 + 31543361 = 31543654
353 + 31543301 = 31543654
431 + 31543223 = 31543654
491 + 31543163 = 31543654

Showing the first eight; more decompositions exist.
