Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461670, here are decompositions:

17 + 31461653 = 31461670
29 + 31461641 = 31461670
101 + 31461569 = 31461670
113 + 31461557 = 31461670
137 + 31461533 = 31461670
257 + 31461413 = 31461670
389 + 31461281 = 31461670
479 + 31461191 = 31461670

Showing the first eight; more decompositions exist.
