Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524938, here are decompositions:

331 + 31524607 = 31524938
397 + 31524541 = 31524938
421 + 31524517 = 31524938
439 + 31524499 = 31524938
607 + 31524331 = 31524938
661 + 31524277 = 31524938
997 + 31523941 = 31524938
1021 + 31523917 = 31524938

Showing the first eight; more decompositions exist.
