Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514848, here are decompositions:

11 + 31514837 = 31514848
59 + 31514789 = 31514848
107 + 31514741 = 31514848
269 + 31514579 = 31514848
311 + 31514537 = 31514848
419 + 31514429 = 31514848
557 + 31514291 = 31514848
587 + 31514261 = 31514848

Showing the first eight; more decompositions exist.
