Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604544, here are decompositions:

11 + 31604533 = 31604544
43 + 31604501 = 31604544
47 + 31604497 = 31604544
157 + 31604387 = 31604544
173 + 31604371 = 31604544
197 + 31604347 = 31604544
233 + 31604311 = 31604544
241 + 31604303 = 31604544

Showing the first eight; more decompositions exist.
