Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731258, here are decompositions:

47 + 8731211 = 8731258
71 + 8731187 = 8731258
149 + 8731109 = 8731258
227 + 8731031 = 8731258
281 + 8730977 = 8731258
311 + 8730947 = 8731258
401 + 8730857 = 8731258
461 + 8730797 = 8731258

Showing the first eight; more decompositions exist.
