Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971272, here are decompositions:
- 3 + 4294971269 = 4294971272
- 73 + 4294971199 = 4294971272
- 103 + 4294971169 = 4294971272
- 199 + 4294971073 = 4294971272
- 349 + 4294970923 = 4294971272
- 409 + 4294970863 = 4294971272
- 433 + 4294970839 = 4294971272
- 523 + 4294970749 = 4294971272
Showing the first eight; more decompositions exist.
