Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466830, here are decompositions:

71 + 31466759 = 31466830
137 + 31466693 = 31466830
173 + 31466657 = 31466830
233 + 31466597 = 31466830
281 + 31466549 = 31466830
443 + 31466387 = 31466830
449 + 31466381 = 31466830
503 + 31466327 = 31466830

Showing the first eight; more decompositions exist.
