Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72698, here are decompositions:
- 19 + 72679 = 72698
- 37 + 72661 = 72698
- 139 + 72559 = 72698
- 151 + 72547 = 72698
- 229 + 72469 = 72698
- 277 + 72421 = 72698
- 331 + 72367 = 72698
- 421 + 72277 = 72698
Showing the first eight; more decompositions exist.
