Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732040, here are decompositions:

11 + 8732029 = 8732040
13 + 8732027 = 8732040
17 + 8732023 = 8732040
47 + 8731993 = 8732040
59 + 8731981 = 8732040
61 + 8731979 = 8732040
89 + 8731951 = 8732040
101 + 8731939 = 8732040

Showing the first eight; more decompositions exist.
