Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973478, here are decompositions:
- 71 + 4294973407 = 4294973478
- 157 + 4294973321 = 4294973478
- 197 + 4294973281 = 4294973478
- 277 + 4294973201 = 4294973478
- 331 + 4294973147 = 4294973478
- 379 + 4294973099 = 4294973478
- 409 + 4294973069 = 4294973478
- 461 + 4294973017 = 4294973478
Showing the first eight; more decompositions exist.
