Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105398, here are decompositions:
- 19 + 105379 = 105398
- 31 + 105367 = 105398
- 37 + 105361 = 105398
- 61 + 105337 = 105398
- 67 + 105331 = 105398
- 79 + 105319 = 105398
- 199 + 105199 = 105398
- 367 + 105031 = 105398
Showing the first eight; more decompositions exist.
