Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731392, here are decompositions:

11 + 8731381 = 8731392
23 + 8731369 = 8731392
29 + 8731363 = 8731392
53 + 8731339 = 8731392
71 + 8731321 = 8731392
79 + 8731313 = 8731392
83 + 8731309 = 8731392
179 + 8731213 = 8731392

Showing the first eight; more decompositions exist.
