Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99000, here are decompositions:
- 7 + 98993 = 99000
- 19 + 98981 = 99000
- 37 + 98963 = 99000
- 47 + 98953 = 99000
- 53 + 98947 = 99000
- 61 + 98939 = 99000
- 71 + 98929 = 99000
- 73 + 98927 = 99000
Showing the first eight; more decompositions exist.
