Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524578, here are decompositions:

37 + 31524541 = 31524578
61 + 31524517 = 31524578
79 + 31524499 = 31524578
109 + 31524469 = 31524578
277 + 31524301 = 31524578
307 + 31524271 = 31524578
487 + 31524091 = 31524578
661 + 31523917 = 31524578

Showing the first eight; more decompositions exist.
