Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978972, here are decompositions:
- 23 + 4294978949 = 4294978972
- 173 + 4294978799 = 4294978972
- 191 + 4294978781 = 4294978972
- 239 + 4294978733 = 4294978972
- 293 + 4294978679 = 4294978972
- 311 + 4294978661 = 4294978972
- 419 + 4294978553 = 4294978972
- 461 + 4294978511 = 4294978972
