Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957772, here are decompositions:
- 19 + 4294957753 = 4294957772
- 43 + 4294957729 = 4294957772
- 73 + 4294957699 = 4294957772
- 163 + 4294957609 = 4294957772
- 373 + 4294957399 = 4294957772
- 463 + 4294957309 = 4294957772
- 673 + 4294957099 = 4294957772
- 691 + 4294957081 = 4294957772
Showing the first eight; more decompositions exist.
