Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45012, here are decompositions:
- 5 + 45007 = 45012
- 29 + 44983 = 45012
- 41 + 44971 = 45012
- 53 + 44959 = 45012
- 59 + 44953 = 45012
- 73 + 44939 = 45012
- 103 + 44909 = 45012
- 173 + 44839 = 45012
Showing the first eight; more decompositions exist.
