Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604500, here are decompositions:

3 + 31604497 = 31604500
47 + 31604453 = 31604500
113 + 31604387 = 31604500
197 + 31604303 = 31604500
281 + 31604219 = 31604500
311 + 31604189 = 31604500
401 + 31604099 = 31604500
443 + 31604057 = 31604500

Showing the first eight; more decompositions exist.
