Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523864, here are decompositions:

13 + 31523851 = 31523864
61 + 31523803 = 31523864
103 + 31523761 = 31523864
157 + 31523707 = 31523864
397 + 31523467 = 31523864
457 + 31523407 = 31523864
571 + 31523293 = 31523864
613 + 31523251 = 31523864

Showing the first eight; more decompositions exist.
