Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731522, here are decompositions:

11 + 8731511 = 8731522
29 + 8731493 = 8731522
89 + 8731433 = 8731522
179 + 8731343 = 8731522
311 + 8731211 = 8731522
383 + 8731139 = 8731522
419 + 8731103 = 8731522
491 + 8731031 = 8731522

Showing the first eight; more decompositions exist.
