Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523554, here are decompositions:

17 + 31523537 = 31523554
113 + 31523441 = 31523554
173 + 31523381 = 31523554
311 + 31523243 = 31523554
317 + 31523237 = 31523554
347 + 31523207 = 31523554
353 + 31523201 = 31523554
443 + 31523111 = 31523554

Showing the first eight; more decompositions exist.
