Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543684, here are decompositions:

23 + 31543661 = 31543684
41 + 31543643 = 31543684
113 + 31543571 = 31543684
233 + 31543451 = 31543684
353 + 31543331 = 31543684
383 + 31543301 = 31543684
461 + 31543223 = 31543684
467 + 31543217 = 31543684

Showing the first eight; more decompositions exist.
