Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456602, here are decompositions:

5 + 31456597 = 31456602
13 + 31456589 = 31456602
71 + 31456531 = 31456602
101 + 31456501 = 31456602
173 + 31456429 = 31456602
223 + 31456379 = 31456602
241 + 31456361 = 31456602
271 + 31456331 = 31456602

Showing the first eight; more decompositions exist.
