Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513332, here are decompositions:

23 + 31513309 = 31513332
29 + 31513303 = 31513332
73 + 31513259 = 31513332
113 + 31513219 = 31513332
131 + 31513201 = 31513332
139 + 31513193 = 31513332
241 + 31513091 = 31513332
269 + 31513063 = 31513332

Showing the first eight; more decompositions exist.
