Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87194, here are decompositions:
- 7 + 87187 = 87194
- 13 + 87181 = 87194
- 43 + 87151 = 87194
- 61 + 87133 = 87194
- 73 + 87121 = 87194
- 157 + 87037 = 87194
- 181 + 87013 = 87194
- 271 + 86923 = 87194
Showing the first eight; more decompositions exist.
