Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957142, here are decompositions:

19 + 4294957123 = 4294957142
43 + 4294957099 = 4294957142
61 + 4294957081 = 4294957142
193 + 4294956949 = 4294957142
241 + 4294956901 = 4294957142
313 + 4294956829 = 4294957142
349 + 4294956793 = 4294957142
499 + 4294956643 = 4294957142

Showing the first eight; more decompositions exist.
