Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38642, here are decompositions:
- 3 + 38639 = 38642
- 13 + 38629 = 38642
- 31 + 38611 = 38642
- 73 + 38569 = 38642
- 181 + 38461 = 38642
- 193 + 38449 = 38642
- 211 + 38431 = 38642
- 271 + 38371 = 38642
Showing the first eight; more decompositions exist.
