Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731498, here are decompositions:

5 + 8731493 = 8731498
71 + 8731427 = 8731498
197 + 8731301 = 8731498
311 + 8731187 = 8731498
359 + 8731139 = 8731498
389 + 8731109 = 8731498
401 + 8731097 = 8731498
467 + 8731031 = 8731498

Showing the first eight; more decompositions exist.
