Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731214, here are decompositions:

3 + 8731211 = 8731214
13 + 8731201 = 8731214
61 + 8731153 = 8731214
73 + 8731141 = 8731214
103 + 8731111 = 8731214
313 + 8730901 = 8731214
367 + 8730847 = 8731214
421 + 8730793 = 8731214

Showing the first eight; more decompositions exist.
