Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479488, here are decompositions:

31 + 31479457 = 31479488
67 + 31479421 = 31479488
151 + 31479337 = 31479488
181 + 31479307 = 31479488
199 + 31479289 = 31479488
211 + 31479277 = 31479488
457 + 31479031 = 31479488
487 + 31479001 = 31479488

Showing the first eight; more decompositions exist.
