Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90912, here are decompositions:
- 5 + 90907 = 90912
- 11 + 90901 = 90912
- 71 + 90841 = 90912
- 79 + 90833 = 90912
- 89 + 90823 = 90912
- 109 + 90803 = 90912
- 163 + 90749 = 90912
- 181 + 90731 = 90912
Showing the first eight; more decompositions exist.
