Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601200, here are decompositions:

101 + 31601099 = 31601200
149 + 31601051 = 31601200
317 + 31600883 = 31601200
383 + 31600817 = 31601200
401 + 31600799 = 31601200
467 + 31600733 = 31601200
479 + 31600721 = 31601200
677 + 31600523 = 31601200

Showing the first eight; more decompositions exist.
