Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97218, here are decompositions:
- 5 + 97213 = 97218
- 31 + 97187 = 97218
- 41 + 97177 = 97218
- 47 + 97171 = 97218
- 59 + 97159 = 97218
- 61 + 97157 = 97218
- 67 + 97151 = 97218
- 101 + 97117 = 97218
Showing the first eight; more decompositions exist.
