Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524692, here are decompositions:

19 + 31524673 = 31524692
151 + 31524541 = 31524692
193 + 31524499 = 31524692
223 + 31524469 = 31524692
349 + 31524343 = 31524692
421 + 31524271 = 31524692
499 + 31524193 = 31524692
601 + 31524091 = 31524692

Showing the first eight; more decompositions exist.
