Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463248, here are decompositions:
- 101 + 31463147 = 31463248
- 149 + 31463099 = 31463248
- 269 + 31462979 = 31463248
- 317 + 31462931 = 31463248
- 347 + 31462901 = 31463248
- 359 + 31462889 = 31463248
- 491 + 31462757 = 31463248
- 599 + 31462649 = 31463248
Showing the first eight; more decompositions exist.
