Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542368, here are decompositions:
- 139 + 31542229 = 31542368
- 331 + 31542037 = 31542368
- 337 + 31542031 = 31542368
- 367 + 31542001 = 31542368
- 379 + 31541989 = 31542368
- 397 + 31541971 = 31542368
- 499 + 31541869 = 31542368
- 541 + 31541827 = 31542368
Showing the first eight; more decompositions exist.
