Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113218, here are decompositions:
- 5 + 113213 = 113218
- 29 + 113189 = 113218
- 41 + 113177 = 113218
- 47 + 113171 = 113218
- 59 + 113159 = 113218
- 71 + 113147 = 113218
- 101 + 113117 = 113218
- 107 + 113111 = 113218
Showing the first eight; more decompositions exist.
