Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604184, here are decompositions:

47 + 31604137 = 31604184
127 + 31604057 = 31604184
151 + 31604033 = 31604184
193 + 31603991 = 31604184
197 + 31603987 = 31604184
251 + 31603933 = 31604184
307 + 31603877 = 31604184
383 + 31603801 = 31604184

Showing the first eight; more decompositions exist.
