Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524618, here are decompositions:

11 + 31524607 = 31524618
31 + 31524587 = 31524618
101 + 31524517 = 31524618
109 + 31524509 = 31524618
149 + 31524469 = 31524618
199 + 31524419 = 31524618
317 + 31524301 = 31524618
347 + 31524271 = 31524618

Showing the first eight; more decompositions exist.
