Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524292, here are decompositions:

131 + 31524161 = 31524292
269 + 31524023 = 31524292
281 + 31524011 = 31524292
353 + 31523939 = 31524292
491 + 31523801 = 31524292
641 + 31523651 = 31524292
659 + 31523633 = 31524292
881 + 31523411 = 31524292

Showing the first eight; more decompositions exist.
