Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456574, here are decompositions:

43 + 31456531 = 31456574
73 + 31456501 = 31456574
283 + 31456291 = 31456574
337 + 31456237 = 31456574
571 + 31456003 = 31456574
613 + 31455961 = 31456574
673 + 31455901 = 31456574
733 + 31455841 = 31456574

Showing the first eight; more decompositions exist.
