Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604476, here are decompositions:

23 + 31604453 = 31604476
89 + 31604387 = 31604476
173 + 31604303 = 31604476
179 + 31604297 = 31604476
257 + 31604219 = 31604476
347 + 31604129 = 31604476
419 + 31604057 = 31604476
443 + 31604033 = 31604476

Showing the first eight; more decompositions exist.
