Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29142, here are decompositions:
- 5 + 29137 = 29142
- 11 + 29131 = 29142
- 13 + 29129 = 29142
- 19 + 29123 = 29142
- 41 + 29101 = 29142
- 79 + 29063 = 29142
- 83 + 29059 = 29142
- 109 + 29033 = 29142
Showing the first eight; more decompositions exist.
