Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958578, here are decompositions:

41 + 4294958537 = 4294958578
479 + 4294958099 = 4294958578
509 + 4294958069 = 4294958578
587 + 4294957991 = 4294958578
719 + 4294957859 = 4294958578
797 + 4294957781 = 4294958578
881 + 4294957697 = 4294958578
1181 + 4294957397 = 4294958578

Showing the first eight; more decompositions exist.
