Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973138, here are decompositions:
- 37 + 4294973101 = 4294973138
- 67 + 4294973071 = 4294973138
- 241 + 4294972897 = 4294973138
- 271 + 4294972867 = 4294973138
- 277 + 4294972861 = 4294973138
- 331 + 4294972807 = 4294973138
- 349 + 4294972789 = 4294973138
- 571 + 4294972567 = 4294973138
Showing the first eight; more decompositions exist.
