Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88990, here are decompositions:
- 53 + 88937 = 88990
- 71 + 88919 = 88990
- 107 + 88883 = 88990
- 137 + 88853 = 88990
- 173 + 88817 = 88990
- 179 + 88811 = 88990
- 191 + 88799 = 88990
- 197 + 88793 = 88990
Showing the first eight; more decompositions exist.
