Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187184, here are decompositions:
- 3 + 187181 = 187184
- 7 + 187177 = 187184
- 13 + 187171 = 187184
- 43 + 187141 = 187184
- 61 + 187123 = 187184
- 73 + 187111 = 187184
- 103 + 187081 = 187184
- 157 + 187027 = 187184
Showing the first eight; more decompositions exist.
