Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11642, here are decompositions:
- 139 + 11503 = 11642
- 151 + 11491 = 11642
- 199 + 11443 = 11642
- 313 + 11329 = 11642
- 331 + 11311 = 11642
- 523 + 11119 = 11642
- 571 + 11071 = 11642
- 733 + 10909 = 11642
Showing the first eight; more decompositions exist.
