Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731270, here are decompositions:

59 + 8731211 = 8731270
83 + 8731187 = 8731270
131 + 8731139 = 8731270
167 + 8731103 = 8731270
173 + 8731097 = 8731270
239 + 8731031 = 8731270
293 + 8730977 = 8731270
389 + 8730881 = 8731270

Showing the first eight; more decompositions exist.
