Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971892, here are decompositions:
- 389 + 4294971503 = 4294971892
- 401 + 4294971491 = 4294971892
- 461 + 4294971431 = 4294971892
- 503 + 4294971389 = 4294971892
- 569 + 4294971323 = 4294971892
- 683 + 4294971209 = 4294971892
- 983 + 4294970909 = 4294971892
- 1013 + 4294970879 = 4294971892
Showing the first eight; more decompositions exist.
