Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45000, here are decompositions:
- 13 + 44987 = 45000
- 17 + 44983 = 45000
- 29 + 44971 = 45000
- 37 + 44963 = 45000
- 41 + 44959 = 45000
- 47 + 44953 = 45000
- 61 + 44939 = 45000
- 73 + 44927 = 45000
Showing the first eight; more decompositions exist.
