Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604532, here are decompositions:

23 + 31604509 = 31604532
31 + 31604501 = 31604532
79 + 31604453 = 31604532
149 + 31604383 = 31604532
173 + 31604359 = 31604532
191 + 31604341 = 31604532
229 + 31604303 = 31604532
233 + 31604299 = 31604532

Showing the first eight; more decompositions exist.
