Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11438, here are decompositions:
- 109 + 11329 = 11438
- 127 + 11311 = 11438
- 139 + 11299 = 11438
- 151 + 11287 = 11438
- 181 + 11257 = 11438
- 199 + 11239 = 11438
- 241 + 11197 = 11438
- 277 + 11161 = 11438
Showing the first eight; more decompositions exist.
