Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520014, here are decompositions:

3 + 31520011 = 31520014
5 + 31520009 = 31520014
137 + 31519877 = 31520014
191 + 31519823 = 31520014
311 + 31519703 = 31520014
353 + 31519661 = 31520014
431 + 31519583 = 31520014
443 + 31519571 = 31520014

Showing the first eight; more decompositions exist.
