Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604454, here are decompositions:

67 + 31604387 = 31604454
71 + 31604383 = 31604454
83 + 31604371 = 31604454
97 + 31604357 = 31604454
107 + 31604347 = 31604454
113 + 31604341 = 31604454
151 + 31604303 = 31604454
157 + 31604297 = 31604454

Showing the first eight; more decompositions exist.
