Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26142, here are decompositions:
- 23 + 26119 = 26142
- 29 + 26113 = 26142
- 31 + 26111 = 26142
- 43 + 26099 = 26142
- 59 + 26083 = 26142
- 89 + 26053 = 26142
- 101 + 26041 = 26142
- 113 + 26029 = 26142
Showing the first eight; more decompositions exist.
