Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731342, here are decompositions:

3 + 8731339 = 8731342
29 + 8731313 = 8731342
41 + 8731301 = 8731342
131 + 8731211 = 8731342
233 + 8731109 = 8731342
239 + 8731103 = 8731342
311 + 8731031 = 8731342
359 + 8730983 = 8731342

Showing the first eight; more decompositions exist.
