Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543308, here are decompositions:

7 + 31543301 = 31543308
89 + 31543219 = 31543308
101 + 31543207 = 31543308
127 + 31543181 = 31543308
229 + 31543079 = 31543308
239 + 31543069 = 31543308
241 + 31543067 = 31543308
317 + 31542991 = 31543308

Showing the first eight; more decompositions exist.
