Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701380, here are decompositions:

13 + 8701367 = 8701380
31 + 8701349 = 8701380
59 + 8701321 = 8701380
71 + 8701309 = 8701380
101 + 8701279 = 8701380
109 + 8701271 = 8701380
113 + 8701267 = 8701380
137 + 8701243 = 8701380

Showing the first eight; more decompositions exist.
