Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45030, here are decompositions:
- 17 + 45013 = 45030
- 23 + 45007 = 45030
- 43 + 44987 = 45030
- 47 + 44983 = 45030
- 59 + 44971 = 45030
- 67 + 44963 = 45030
- 71 + 44959 = 45030
- 103 + 44927 = 45030
Showing the first eight; more decompositions exist.
