Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31194, here are decompositions:
- 5 + 31189 = 31194
- 11 + 31183 = 31194
- 13 + 31181 = 31194
- 17 + 31177 = 31194
- 41 + 31153 = 31194
- 43 + 31151 = 31194
- 47 + 31147 = 31194
- 71 + 31123 = 31194
Showing the first eight; more decompositions exist.
