Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972678, here are decompositions:
- 197 + 4294972481 = 4294972678
- 257 + 4294972421 = 4294972678
- 569 + 4294972109 = 4294972678
- 599 + 4294972079 = 4294972678
- 617 + 4294972061 = 4294972678
- 641 + 4294972037 = 4294972678
- 1181 + 4294971497 = 4294972678
- 1187 + 4294971491 = 4294972678
Showing the first eight; more decompositions exist.
