Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568342, here are decompositions:

31 + 31568311 = 31568342
61 + 31568281 = 31568342
139 + 31568203 = 31568342
163 + 31568179 = 31568342
271 + 31568071 = 31568342
283 + 31568059 = 31568342
523 + 31567819 = 31568342
601 + 31567741 = 31568342

Showing the first eight; more decompositions exist.
