Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73642, here are decompositions:
- 5 + 73637 = 73642
- 29 + 73613 = 73642
- 53 + 73589 = 73642
- 59 + 73583 = 73642
- 71 + 73571 = 73642
- 89 + 73553 = 73642
- 113 + 73529 = 73642
- 263 + 73379 = 73642
Showing the first eight; more decompositions exist.
