Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604506, here are decompositions:

5 + 31604501 = 31604506
53 + 31604453 = 31604506
149 + 31604357 = 31604506
317 + 31604189 = 31604506
449 + 31604057 = 31604506
587 + 31603919 = 31604506
617 + 31603889 = 31604506
677 + 31603829 = 31604506

Showing the first eight; more decompositions exist.
