Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604236, here are decompositions:

17 + 31604219 = 31604236
47 + 31604189 = 31604236
107 + 31604129 = 31604236
137 + 31604099 = 31604236
179 + 31604057 = 31604236
317 + 31603919 = 31604236
347 + 31603889 = 31604236
359 + 31603877 = 31604236

Showing the first eight; more decompositions exist.
