Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460848, here are decompositions:

11 + 31460837 = 31460848
17 + 31460831 = 31460848
131 + 31460717 = 31460848
191 + 31460657 = 31460848
239 + 31460609 = 31460848
311 + 31460537 = 31460848
449 + 31460399 = 31460848
479 + 31460369 = 31460848

Showing the first eight; more decompositions exist.
