Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568372, here are decompositions:

19 + 31568353 = 31568372
61 + 31568311 = 31568372
151 + 31568221 = 31568372
193 + 31568179 = 31568372
313 + 31568059 = 31568372
331 + 31568041 = 31568372
373 + 31567999 = 31568372
523 + 31567849 = 31568372

Showing the first eight; more decompositions exist.
