Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513350, here are decompositions:

17 + 31513333 = 31513350
19 + 31513331 = 31513350
41 + 31513309 = 31513350
47 + 31513303 = 31513350
131 + 31513219 = 31513350
137 + 31513213 = 31513350
149 + 31513201 = 31513350
157 + 31513193 = 31513350

Showing the first eight; more decompositions exist.
