Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957890, here are decompositions:

29 + 4294957861 = 4294957890
31 + 4294957859 = 4294957890
37 + 4294957853 = 4294957890
109 + 4294957781 = 4294957890
137 + 4294957753 = 4294957890
173 + 4294957717 = 4294957890
191 + 4294957699 = 4294957890
193 + 4294957697 = 4294957890

Showing the first eight; more decompositions exist.
