Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70212, here are decompositions:
- 5 + 70207 = 70212
- 11 + 70201 = 70212
- 13 + 70199 = 70212
- 29 + 70183 = 70212
- 31 + 70181 = 70212
- 71 + 70141 = 70212
- 73 + 70139 = 70212
- 89 + 70123 = 70212
Showing the first eight; more decompositions exist.
