Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482680, here are decompositions:

13 + 31482667 = 31482680
37 + 31482643 = 31482680
67 + 31482613 = 31482680
181 + 31482499 = 31482680
241 + 31482439 = 31482680
331 + 31482349 = 31482680
337 + 31482343 = 31482680
373 + 31482307 = 31482680

Showing the first eight; more decompositions exist.
