Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604444, here are decompositions:

61 + 31604383 = 31604444
73 + 31604371 = 31604444
97 + 31604347 = 31604444
103 + 31604341 = 31604444
163 + 31604281 = 31604444
181 + 31604263 = 31604444
307 + 31604137 = 31604444
457 + 31603987 = 31604444

Showing the first eight; more decompositions exist.
