Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524194, here are decompositions:

61 + 31524133 = 31524194
103 + 31524091 = 31524194
151 + 31524043 = 31524194
181 + 31524013 = 31524194
241 + 31523953 = 31524194
277 + 31523917 = 31524194
313 + 31523881 = 31524194
433 + 31523761 = 31524194

Showing the first eight; more decompositions exist.
