Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531114, here are decompositions:

113 + 31531001 = 31531114
137 + 31530977 = 31531114
281 + 31530833 = 31531114
317 + 31530797 = 31531114
401 + 31530713 = 31531114
431 + 31530683 = 31531114
521 + 31530593 = 31531114
617 + 31530497 = 31531114

Showing the first eight; more decompositions exist.
