Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989920, here are decompositions:

7 + 4294989913 = 4294989920
37 + 4294989883 = 4294989920
43 + 4294989877 = 4294989920
103 + 4294989817 = 4294989920
139 + 4294989781 = 4294989920
271 + 4294989649 = 4294989920
337 + 4294989583 = 4294989920
367 + 4294989553 = 4294989920

Showing the first eight; more decompositions exist.
