Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973990, here are decompositions:

3 + 4294973987 = 4294973990
37 + 4294973953 = 4294973990
67 + 4294973923 = 4294973990
79 + 4294973911 = 4294973990
199 + 4294973791 = 4294973990
277 + 4294973713 = 4294973990
379 + 4294973611 = 4294973990
397 + 4294973593 = 4294973990

Showing the first eight; more decompositions exist.
