Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45140, here are decompositions:
- 3 + 45137 = 45140
- 13 + 45127 = 45140
- 19 + 45121 = 45140
- 79 + 45061 = 45140
- 127 + 45013 = 45140
- 157 + 44983 = 45140
- 181 + 44959 = 45140
- 223 + 44917 = 45140
Showing the first eight; more decompositions exist.
