Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31048, here are decompositions:
- 29 + 31019 = 31048
- 71 + 30977 = 31048
- 107 + 30941 = 31048
- 137 + 30911 = 31048
- 167 + 30881 = 31048
- 179 + 30869 = 31048
- 197 + 30851 = 31048
- 239 + 30809 = 31048
Showing the first eight; more decompositions exist.
