Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567342, here are decompositions:

29 + 31567313 = 31567342
71 + 31567271 = 31567342
101 + 31567241 = 31567342
251 + 31567091 = 31567342
293 + 31567049 = 31567342
431 + 31566911 = 31567342
479 + 31566863 = 31567342
503 + 31566839 = 31567342

Showing the first eight; more decompositions exist.
