Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485488, here are decompositions:

61 + 31485427 = 31485488
109 + 31485379 = 31485488
211 + 31485277 = 31485488
241 + 31485247 = 31485488
367 + 31485121 = 31485488
409 + 31485079 = 31485488
421 + 31485067 = 31485488
439 + 31485049 = 31485488

Showing the first eight; more decompositions exist.
