Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45978, here are decompositions:
- 7 + 45971 = 45978
- 19 + 45959 = 45978
- 29 + 45949 = 45978
- 109 + 45869 = 45978
- 137 + 45841 = 45978
- 151 + 45827 = 45978
- 157 + 45821 = 45978
- 199 + 45779 = 45978
Showing the first eight; more decompositions exist.
