Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523338, here are decompositions:

29 + 31523309 = 31523338
59 + 31523279 = 31523338
71 + 31523267 = 31523338
101 + 31523237 = 31523338
107 + 31523231 = 31523338
131 + 31523207 = 31523338
137 + 31523201 = 31523338
227 + 31523111 = 31523338

Showing the first eight; more decompositions exist.
