Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61312, here are decompositions:
- 29 + 61283 = 61312
- 59 + 61253 = 61312
- 89 + 61223 = 61312
- 101 + 61211 = 61312
- 191 + 61121 = 61312
- 269 + 61043 = 61312
- 281 + 61031 = 61312
- 311 + 61001 = 61312
Showing the first eight; more decompositions exist.
