Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971838, here are decompositions:
- 281 + 4294971557 = 4294971838
- 347 + 4294971491 = 4294971838
- 449 + 4294971389 = 4294971838
- 461 + 4294971377 = 4294971838
- 569 + 4294971269 = 4294971838
- 617 + 4294971221 = 4294971838
- 761 + 4294971077 = 4294971838
- 929 + 4294970909 = 4294971838
Showing the first eight; more decompositions exist.
