Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99140, here are decompositions:
- 3 + 99137 = 99140
- 7 + 99133 = 99140
- 31 + 99109 = 99140
- 37 + 99103 = 99140
- 61 + 99079 = 99140
- 127 + 99013 = 99140
- 193 + 98947 = 99140
- 211 + 98929 = 99140
Showing the first eight; more decompositions exist.
