Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604338, here are decompositions:

41 + 31604297 = 31604338
149 + 31604189 = 31604338
239 + 31604099 = 31604338
281 + 31604057 = 31604338
347 + 31603991 = 31604338
419 + 31603919 = 31604338
449 + 31603889 = 31604338
461 + 31603877 = 31604338

Showing the first eight; more decompositions exist.
