Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471602, here are decompositions:

11 + 31471591 = 31471602
23 + 31471579 = 31471602
53 + 31471549 = 31471602
79 + 31471523 = 31471602
163 + 31471439 = 31471602
191 + 31471411 = 31471602
229 + 31471373 = 31471602
241 + 31471361 = 31471602

Showing the first eight; more decompositions exist.
