Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523344, here are decompositions:

101 + 31523243 = 31523344
107 + 31523237 = 31523344
113 + 31523231 = 31523344
137 + 31523207 = 31523344
233 + 31523111 = 31523344
263 + 31523081 = 31523344
317 + 31523027 = 31523344
383 + 31522961 = 31523344

Showing the first eight; more decompositions exist.
