Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987396, here are decompositions:

3 + 4294987393 = 4294987396
107 + 4294987289 = 4294987396
239 + 4294987157 = 4294987396
443 + 4294986953 = 4294987396
503 + 4294986893 = 4294987396
659 + 4294986737 = 4294987396
1187 + 4294986209 = 4294987396
1289 + 4294986107 = 4294987396

Showing the first eight; more decompositions exist.
