Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699380, here are decompositions:

29 + 8699351 = 8699380
71 + 8699309 = 8699380
83 + 8699297 = 8699380
101 + 8699279 = 8699380
311 + 8699069 = 8699380
317 + 8699063 = 8699380
383 + 8698997 = 8699380
419 + 8698961 = 8699380

Showing the first eight; more decompositions exist.
