Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481414, here are decompositions:

7 + 31481407 = 31481414
31 + 31481383 = 31481414
43 + 31481371 = 31481414
61 + 31481353 = 31481414
73 + 31481341 = 31481414
163 + 31481251 = 31481414
271 + 31481143 = 31481414
313 + 31481101 = 31481414

Showing the first eight; more decompositions exist.
