Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45090, here are decompositions:
- 7 + 45083 = 45090
- 13 + 45077 = 45090
- 29 + 45061 = 45090
- 37 + 45053 = 45090
- 83 + 45007 = 45090
- 103 + 44987 = 45090
- 107 + 44983 = 45090
- 127 + 44963 = 45090
Showing the first eight; more decompositions exist.
