Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90012, here are decompositions:
- 5 + 90007 = 90012
- 11 + 90001 = 90012
- 23 + 89989 = 90012
- 29 + 89983 = 90012
- 53 + 89959 = 90012
- 73 + 89939 = 90012
- 89 + 89923 = 90012
- 103 + 89909 = 90012
Showing the first eight; more decompositions exist.
