Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97212, here are decompositions:
- 41 + 97171 = 97212
- 43 + 97169 = 97212
- 53 + 97159 = 97212
- 61 + 97151 = 97212
- 109 + 97103 = 97212
- 131 + 97081 = 97212
- 139 + 97073 = 97212
- 173 + 97039 = 97212
Showing the first eight; more decompositions exist.
