Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604570, here are decompositions:

13 + 31604557 = 31604570
37 + 31604533 = 31604570
61 + 31604509 = 31604570
73 + 31604497 = 31604570
199 + 31604371 = 31604570
211 + 31604359 = 31604570
223 + 31604347 = 31604570
229 + 31604341 = 31604570

Showing the first eight; more decompositions exist.
