Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567804, here are decompositions:

131 + 31567673 = 31567804
167 + 31567637 = 31567804
251 + 31567553 = 31567804
293 + 31567511 = 31567804
353 + 31567451 = 31567804
491 + 31567313 = 31567804
563 + 31567241 = 31567804
647 + 31567157 = 31567804

Showing the first eight; more decompositions exist.
