Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481714, here are decompositions:

3 + 31481711 = 31481714
13 + 31481701 = 31481714
31 + 31481683 = 31481714
37 + 31481677 = 31481714
193 + 31481521 = 31481714
241 + 31481473 = 31481714
283 + 31481431 = 31481714
307 + 31481407 = 31481714

Showing the first eight; more decompositions exist.
