Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524608, here are decompositions:

67 + 31524541 = 31524608
109 + 31524499 = 31524608
139 + 31524469 = 31524608
277 + 31524331 = 31524608
307 + 31524301 = 31524608
331 + 31524277 = 31524608
337 + 31524271 = 31524608
691 + 31523917 = 31524608

Showing the first eight; more decompositions exist.
