Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499834, here are decompositions:

31 + 31499803 = 31499834
73 + 31499761 = 31499834
103 + 31499731 = 31499834
241 + 31499593 = 31499834
337 + 31499497 = 31499834
367 + 31499467 = 31499834
433 + 31499401 = 31499834
463 + 31499371 = 31499834

Showing the first eight; more decompositions exist.
