Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524624, here are decompositions:

17 + 31524607 = 31524624
37 + 31524587 = 31524624
83 + 31524541 = 31524624
101 + 31524523 = 31524624
107 + 31524517 = 31524624
281 + 31524343 = 31524624
293 + 31524331 = 31524624
331 + 31524293 = 31524624

Showing the first eight; more decompositions exist.
