Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971580, here are decompositions:
- 17 + 4294971563 = 4294971580
- 23 + 4294971557 = 4294971580
- 83 + 4294971497 = 4294971580
- 89 + 4294971491 = 4294971580
- 149 + 4294971431 = 4294971580
- 191 + 4294971389 = 4294971580
- 257 + 4294971323 = 4294971580
- 311 + 4294971269 = 4294971580
Showing the first eight; more decompositions exist.
