Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458602, here are decompositions:

13 + 31458589 = 31458602
61 + 31458541 = 31458602
151 + 31458451 = 31458602
199 + 31458403 = 31458602
223 + 31458379 = 31458602
229 + 31458373 = 31458602
271 + 31458331 = 31458602
433 + 31458169 = 31458602

Showing the first eight; more decompositions exist.
