Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541678, here are decompositions:
- 19 + 31541659 = 31541678
- 67 + 31541611 = 31541678
- 97 + 31541581 = 31541678
- 109 + 31541569 = 31541678
- 151 + 31541527 = 31541678
- 211 + 31541467 = 31541678
- 229 + 31541449 = 31541678
- 241 + 31541437 = 31541678
Showing the first eight; more decompositions exist.
