Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120126, here are decompositions:
- 5 + 120121 = 120126
- 23 + 120103 = 120126
- 29 + 120097 = 120126
- 47 + 120079 = 120126
- 59 + 120067 = 120126
- 79 + 120047 = 120126
- 109 + 120017 = 120126
- 163 + 119963 = 120126
Showing the first eight; more decompositions exist.
