Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604260, here are decompositions:

41 + 31604219 = 31604260
71 + 31604189 = 31604260
131 + 31604129 = 31604260
227 + 31604033 = 31604260
269 + 31603991 = 31604260
383 + 31603877 = 31604260
431 + 31603829 = 31604260
503 + 31603757 = 31604260

Showing the first eight; more decompositions exist.
