Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40142, here are decompositions:
- 13 + 40129 = 40142
- 19 + 40123 = 40142
- 31 + 40111 = 40142
- 43 + 40099 = 40142
- 79 + 40063 = 40142
- 103 + 40039 = 40142
- 163 + 39979 = 40142
- 241 + 39901 = 40142
Showing the first eight; more decompositions exist.
