Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460642, here are decompositions:
- 61 + 31460581 = 31460642
- 151 + 31460491 = 31460642
- 211 + 31460431 = 31460642
- 229 + 31460413 = 31460642
- 313 + 31460329 = 31460642
- 349 + 31460293 = 31460642
- 379 + 31460263 = 31460642
- 643 + 31459999 = 31460642
Showing the first eight; more decompositions exist.
