Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974942, here are decompositions:
- 19 + 4294974923 = 4294974942
- 23 + 4294974919 = 4294974942
- 29 + 4294974913 = 4294974942
- 61 + 4294974881 = 4294974942
- 79 + 4294974863 = 4294974942
- 131 + 4294974811 = 4294974942
- 149 + 4294974793 = 4294974942
- 173 + 4294974769 = 4294974942
Showing the first eight; more decompositions exist.
