Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601312, here are decompositions:

109 + 31601203 = 31601312
229 + 31601083 = 31601312
271 + 31601041 = 31601312
541 + 31600771 = 31601312
571 + 31600741 = 31601312
619 + 31600693 = 31601312
643 + 31600669 = 31601312
859 + 31600453 = 31601312

Showing the first eight; more decompositions exist.
