Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450694, here are decompositions:
- 73 + 31450621 = 31450694
- 151 + 31450543 = 31450694
- 211 + 31450483 = 31450694
- 271 + 31450423 = 31450694
- 283 + 31450411 = 31450694
- 307 + 31450387 = 31450694
- 487 + 31450207 = 31450694
- 577 + 31450117 = 31450694
Showing the first eight; more decompositions exist.
