Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45072, here are decompositions:
- 11 + 45061 = 45072
- 19 + 45053 = 45072
- 59 + 45013 = 45072
- 89 + 44983 = 45072
- 101 + 44971 = 45072
- 109 + 44963 = 45072
- 113 + 44959 = 45072
- 163 + 44909 = 45072
Showing the first eight; more decompositions exist.
