Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499324, here are decompositions:

13 + 31499311 = 31499324
97 + 31499227 = 31499324
163 + 31499161 = 31499324
331 + 31498993 = 31499324
457 + 31498867 = 31499324
487 + 31498837 = 31499324
733 + 31498591 = 31499324
811 + 31498513 = 31499324

Showing the first eight; more decompositions exist.
