Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989990, here are decompositions:

13 + 4294989977 = 4294989990
19 + 4294989971 = 4294989990
41 + 4294989949 = 4294989990
47 + 4294989943 = 4294989990
103 + 4294989887 = 4294989990
107 + 4294989883 = 4294989990
113 + 4294989877 = 4294989990
173 + 4294989817 = 4294989990

Showing the first eight; more decompositions exist.
