Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480040, here are decompositions:
- 19 + 31480021 = 31480040
- 79 + 31479961 = 31480040
- 211 + 31479829 = 31480040
- 223 + 31479817 = 31480040
- 271 + 31479769 = 31480040
- 283 + 31479757 = 31480040
- 421 + 31479619 = 31480040
- 463 + 31479577 = 31480040
Showing the first eight; more decompositions exist.
