Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483876, here are decompositions:

5 + 31483871 = 31483876
227 + 31483649 = 31483876
293 + 31483583 = 31483876
383 + 31483493 = 31483876
419 + 31483457 = 31483876
443 + 31483433 = 31483876
563 + 31483313 = 31483876
569 + 31483307 = 31483876

Showing the first eight; more decompositions exist.
