Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520092, here are decompositions:

3 + 31520089 = 31520092
83 + 31520009 = 31520092
173 + 31519919 = 31520092
269 + 31519823 = 31520092
389 + 31519703 = 31520092
419 + 31519673 = 31520092
431 + 31519661 = 31520092
491 + 31519601 = 31520092

Showing the first eight; more decompositions exist.
