Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957780, here are decompositions:

83 + 4294957697 = 4294957780
101 + 4294957679 = 4294957780
137 + 4294957643 = 4294957780
227 + 4294957553 = 4294957780
257 + 4294957523 = 4294957780
383 + 4294957397 = 4294957780
431 + 4294957349 = 4294957780
461 + 4294957319 = 4294957780

Showing the first eight; more decompositions exist.
