Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604418, here are decompositions:

31 + 31604387 = 31604418
47 + 31604371 = 31604418
59 + 31604359 = 31604418
61 + 31604357 = 31604418
71 + 31604347 = 31604418
107 + 31604311 = 31604418
137 + 31604281 = 31604418
191 + 31604227 = 31604418

Showing the first eight; more decompositions exist.
