Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567450, here are decompositions:

23 + 31567427 = 31567450
53 + 31567397 = 31567450
137 + 31567313 = 31567450
179 + 31567271 = 31567450
293 + 31567157 = 31567450
359 + 31567091 = 31567450
401 + 31567049 = 31567450
587 + 31566863 = 31567450

Showing the first eight; more decompositions exist.
