Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985780, here are decompositions:

97 + 4294985683 = 4294985780
157 + 4294985623 = 4294985780
199 + 4294985581 = 4294985780
313 + 4294985467 = 4294985780
331 + 4294985449 = 4294985780
541 + 4294985239 = 4294985780
739 + 4294985041 = 4294985780
823 + 4294984957 = 4294985780

Showing the first eight; more decompositions exist.
