Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513254, here are decompositions:

41 + 31513213 = 31513254
53 + 31513201 = 31513254
61 + 31513193 = 31513254
67 + 31513187 = 31513254
107 + 31513147 = 31513254
131 + 31513123 = 31513254
137 + 31513117 = 31513254
163 + 31513091 = 31513254

Showing the first eight; more decompositions exist.
