Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483750, here are decompositions:

17 + 31483733 = 31483750
59 + 31483691 = 31483750
101 + 31483649 = 31483750
167 + 31483583 = 31483750
173 + 31483577 = 31483750
197 + 31483553 = 31483750
257 + 31483493 = 31483750
281 + 31483469 = 31483750

Showing the first eight; more decompositions exist.
