Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608242, here are decompositions:

73 + 31608169 = 31608242
79 + 31608163 = 31608242
109 + 31608133 = 31608242
151 + 31608091 = 31608242
181 + 31608061 = 31608242
229 + 31608013 = 31608242
271 + 31607971 = 31608242
373 + 31607869 = 31608242

Showing the first eight; more decompositions exist.
