Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972640, here are decompositions:

31 + 4294972609 = 4294972640
37 + 4294972603 = 4294972640
61 + 4294972579 = 4294972640
73 + 4294972567 = 4294972640
199 + 4294972441 = 4294972640
229 + 4294972411 = 4294972640
307 + 4294972333 = 4294972640
349 + 4294972291 = 4294972640

Showing the first eight; more decompositions exist.
