Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604584, here are decompositions:

23 + 31604561 = 31604584
83 + 31604501 = 31604584
131 + 31604453 = 31604584
197 + 31604387 = 31604584
227 + 31604357 = 31604584
281 + 31604303 = 31604584
593 + 31603991 = 31604584
653 + 31603931 = 31604584

Showing the first eight; more decompositions exist.
