Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482408, here are decompositions:
- 7 + 31482401 = 31482408
- 19 + 31482389 = 31482408
- 59 + 31482349 = 31482408
- 71 + 31482337 = 31482408
- 101 + 31482307 = 31482408
- 127 + 31482281 = 31482408
- 131 + 31482277 = 31482408
- 137 + 31482271 = 31482408
Showing the first eight; more decompositions exist.
