Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567372, here are decompositions:

3 + 31567369 = 31567372
59 + 31567313 = 31567372
101 + 31567271 = 31567372
131 + 31567241 = 31567372
281 + 31567091 = 31567372
461 + 31566911 = 31567372
509 + 31566863 = 31567372
569 + 31566803 = 31567372

Showing the first eight; more decompositions exist.
