Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101398, here are decompositions:
- 131 + 101267 = 101398
- 191 + 101207 = 101398
- 239 + 101159 = 101398
- 257 + 101141 = 101398
- 281 + 101117 = 101398
- 317 + 101081 = 101398
- 347 + 101051 = 101398
- 389 + 101009 = 101398
Showing the first eight; more decompositions exist.
