Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74642, here are decompositions:
- 19 + 74623 = 74642
- 31 + 74611 = 74642
- 193 + 74449 = 74642
- 223 + 74419 = 74642
- 229 + 74413 = 74642
- 331 + 74311 = 74642
- 349 + 74293 = 74642
- 433 + 74209 = 74642
Showing the first eight; more decompositions exist.
