Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121236, here are decompositions:
- 7 + 121229 = 121236
- 47 + 121189 = 121236
- 67 + 121169 = 121236
- 79 + 121157 = 121236
- 97 + 121139 = 121236
- 113 + 121123 = 121236
- 173 + 121063 = 121236
- 197 + 121039 = 121236
Showing the first eight; more decompositions exist.
