Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513602, here are decompositions:

23 + 31513579 = 31513602
41 + 31513561 = 31513602
179 + 31513423 = 31513602
191 + 31513411 = 31513602
199 + 31513403 = 31513602
229 + 31513373 = 31513602
269 + 31513333 = 31513602
271 + 31513331 = 31513602

Showing the first eight; more decompositions exist.
