Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972838, here are decompositions:

31 + 4294972807 = 4294972838
181 + 4294972657 = 4294972838
229 + 4294972609 = 4294972838
271 + 4294972567 = 4294972838
397 + 4294972441 = 4294972838
487 + 4294972351 = 4294972838
547 + 4294972291 = 4294972838
571 + 4294972267 = 4294972838

Showing the first eight; more decompositions exist.
