Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567230, here are decompositions:

11 + 31567219 = 31567230
17 + 31567213 = 31567230
73 + 31567157 = 31567230
139 + 31567091 = 31567230
181 + 31567049 = 31567230
251 + 31566979 = 31567230
257 + 31566973 = 31567230
263 + 31566967 = 31567230

Showing the first eight; more decompositions exist.
