Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66254, here are decompositions:
- 151 + 66103 = 66254
- 271 + 65983 = 66254
- 373 + 65881 = 66254
- 523 + 65731 = 66254
- 541 + 65713 = 66254
- 547 + 65707 = 66254
- 577 + 65677 = 66254
- 607 + 65647 = 66254
Showing the first eight; more decompositions exist.
