Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731582, here are decompositions:

3 + 8731579 = 8731582
11 + 8731571 = 8731582
53 + 8731529 = 8731582
71 + 8731511 = 8731582
89 + 8731493 = 8731582
149 + 8731433 = 8731582
239 + 8731343 = 8731582
269 + 8731313 = 8731582

Showing the first eight; more decompositions exist.
