Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72818, here are decompositions:
- 79 + 72739 = 72818
- 139 + 72679 = 72818
- 157 + 72661 = 72818
- 241 + 72577 = 72818
- 271 + 72547 = 72818
- 337 + 72481 = 72818
- 349 + 72469 = 72818
- 397 + 72421 = 72818
Showing the first eight; more decompositions exist.
