Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971242, here are decompositions:
- 43 + 4294971199 = 4294971242
- 73 + 4294971169 = 4294971242
- 379 + 4294970863 = 4294971242
- 673 + 4294970569 = 4294971242
- 739 + 4294970503 = 4294971242
- 1093 + 4294970149 = 4294971242
- 1153 + 4294970089 = 4294971242
- 1249 + 4294969993 = 4294971242
Showing the first eight; more decompositions exist.
