Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604652, here are decompositions:

5 + 31604647 = 31604652
11 + 31604641 = 31604652
41 + 31604611 = 31604652
43 + 31604609 = 31604652
151 + 31604501 = 31604652
199 + 31604453 = 31604652
269 + 31604383 = 31604652
281 + 31604371 = 31604652

Showing the first eight; more decompositions exist.
