Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458670, here are decompositions:
- 3 + 31458667 = 31458670
- 83 + 31458587 = 31458670
- 233 + 31458437 = 31458670
- 239 + 31458431 = 31458670
- 251 + 31458419 = 31458670
- 293 + 31458377 = 31458670
- 359 + 31458311 = 31458670
- 431 + 31458239 = 31458670
Showing the first eight; more decompositions exist.
