Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521092, here are decompositions:

61 + 31521031 = 31521092
181 + 31520911 = 31521092
193 + 31520899 = 31521092
241 + 31520851 = 31521092
331 + 31520761 = 31521092
373 + 31520719 = 31521092
433 + 31520659 = 31521092
523 + 31520569 = 31521092

Showing the first eight; more decompositions exist.
