Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4642, here are decompositions:
- 3 + 4639 = 4642
- 5 + 4637 = 4642
- 59 + 4583 = 4642
- 149 + 4493 = 4642
- 179 + 4463 = 4642
- 191 + 4451 = 4642
- 233 + 4409 = 4642
- 251 + 4391 = 4642
Showing the first eight; more decompositions exist.
