Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449264, here are decompositions:
- 5 + 31449259 = 31449264
- 17 + 31449247 = 31449264
- 23 + 31449241 = 31449264
- 31 + 31449233 = 31449264
- 73 + 31449191 = 31449264
- 101 + 31449163 = 31449264
- 137 + 31449127 = 31449264
- 181 + 31449083 = 31449264
Showing the first eight; more decompositions exist.
