Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461700, here are decompositions:

3 + 31461697 = 31461700
47 + 31461653 = 31461700
59 + 31461641 = 31461700
131 + 31461569 = 31461700
167 + 31461533 = 31461700
359 + 31461341 = 31461700
419 + 31461281 = 31461700
509 + 31461191 = 31461700

Showing the first eight; more decompositions exist.
