Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608602, here are decompositions:

13 + 31608589 = 31608602
73 + 31608529 = 31608602
283 + 31608319 = 31608602
331 + 31608271 = 31608602
433 + 31608169 = 31608602
439 + 31608163 = 31608602
541 + 31608061 = 31608602
631 + 31607971 = 31608602

Showing the first eight; more decompositions exist.
