Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458718, here are decompositions:
- 17 + 31458701 = 31458718
- 29 + 31458689 = 31458718
- 131 + 31458587 = 31458718
- 191 + 31458527 = 31458718
- 281 + 31458437 = 31458718
- 419 + 31458299 = 31458718
- 479 + 31458239 = 31458718
- 521 + 31458197 = 31458718
Showing the first eight; more decompositions exist.
