Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90988, here are decompositions:
- 11 + 90977 = 90988
- 17 + 90971 = 90988
- 41 + 90947 = 90988
- 71 + 90917 = 90988
- 101 + 90887 = 90988
- 167 + 90821 = 90988
- 239 + 90749 = 90988
- 257 + 90731 = 90988
Showing the first eight; more decompositions exist.
