Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971428, here are decompositions:
- 37 + 4294971391 = 4294971428
- 61 + 4294971367 = 4294971428
- 79 + 4294971349 = 4294971428
- 127 + 4294971301 = 4294971428
- 229 + 4294971199 = 4294971428
- 277 + 4294971151 = 4294971428
- 331 + 4294971097 = 4294971428
- 859 + 4294970569 = 4294971428
Showing the first eight; more decompositions exist.
