Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10120, here are decompositions:
- 17 + 10103 = 10120
- 29 + 10091 = 10120
- 41 + 10079 = 10120
- 53 + 10067 = 10120
- 59 + 10061 = 10120
- 83 + 10037 = 10120
- 113 + 10007 = 10120
- 179 + 9941 = 10120
Showing the first eight; more decompositions exist.
