Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524698, here are decompositions:

157 + 31524541 = 31524698
181 + 31524517 = 31524698
199 + 31524499 = 31524698
229 + 31524469 = 31524698
367 + 31524331 = 31524698
397 + 31524301 = 31524698
421 + 31524277 = 31524698
607 + 31524091 = 31524698

Showing the first eight; more decompositions exist.
