Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90072, here are decompositions:
- 5 + 90067 = 90072
- 13 + 90059 = 90072
- 19 + 90053 = 90072
- 41 + 90031 = 90072
- 53 + 90019 = 90072
- 61 + 90011 = 90072
- 71 + 90001 = 90072
- 83 + 89989 = 90072
Showing the first eight; more decompositions exist.
