Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524338, here are decompositions:

7 + 31524331 = 31524338
37 + 31524301 = 31524338
61 + 31524277 = 31524338
67 + 31524271 = 31524338
397 + 31523941 = 31524338
421 + 31523917 = 31524338
457 + 31523881 = 31524338
487 + 31523851 = 31524338

Showing the first eight; more decompositions exist.
