Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26190, here are decompositions:
- 7 + 26183 = 26190
- 13 + 26177 = 26190
- 19 + 26171 = 26190
- 29 + 26161 = 26190
- 37 + 26153 = 26190
- 71 + 26119 = 26190
- 79 + 26111 = 26190
- 83 + 26107 = 26190
Showing the first eight; more decompositions exist.
