Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485232, here are decompositions:
- 11 + 31485221 = 31485232
- 41 + 31485191 = 31485232
- 131 + 31485101 = 31485232
- 173 + 31485059 = 31485232
- 239 + 31484993 = 31485232
- 431 + 31484801 = 31485232
- 461 + 31484771 = 31485232
- 479 + 31484753 = 31485232
Showing the first eight; more decompositions exist.
