Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1212, here are decompositions:
- 11 + 1201 = 1212
- 19 + 1193 = 1212
- 31 + 1181 = 1212
- 41 + 1171 = 1212
- 59 + 1153 = 1212
- 61 + 1151 = 1212
- 83 + 1129 = 1212
- 89 + 1123 = 1212
Showing the first eight; more decompositions exist.
