Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477248, here are decompositions:
- 41 + 31477207 = 31477248
- 67 + 31477181 = 31477248
- 107 + 31477141 = 31477248
- 137 + 31477111 = 31477248
- 149 + 31477099 = 31477248
- 181 + 31477067 = 31477248
- 191 + 31477057 = 31477248
- 197 + 31477051 = 31477248
Showing the first eight; more decompositions exist.
