Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524442, here are decompositions:

23 + 31524419 = 31524442
149 + 31524293 = 31524442
281 + 31524161 = 31524442
419 + 31524023 = 31524442
431 + 31524011 = 31524442
503 + 31523939 = 31524442
641 + 31523801 = 31524442
773 + 31523669 = 31524442

Showing the first eight; more decompositions exist.
