Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542298, here are decompositions:

17 + 31542281 = 31542298
101 + 31542197 = 31542298
149 + 31542149 = 31542298
317 + 31541981 = 31542298
647 + 31541651 = 31542298
701 + 31541597 = 31542298
881 + 31541417 = 31542298
1031 + 31541267 = 31542298

Showing the first eight; more decompositions exist.
