Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454700, here are decompositions:

19 + 31454681 = 31454700
31 + 31454669 = 31454700
47 + 31454653 = 31454700
73 + 31454627 = 31454700
113 + 31454587 = 31454700
239 + 31454461 = 31454700
269 + 31454431 = 31454700
311 + 31454389 = 31454700

Showing the first eight; more decompositions exist.
