Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731372, here are decompositions:

3 + 8731369 = 8731372
29 + 8731343 = 8731372
59 + 8731313 = 8731372
71 + 8731301 = 8731372
233 + 8731139 = 8731372
263 + 8731109 = 8731372
269 + 8731103 = 8731372
389 + 8730983 = 8731372

Showing the first eight; more decompositions exist.
