Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72036, here are decompositions:
- 5 + 72031 = 72036
- 17 + 72019 = 72036
- 37 + 71999 = 72036
- 43 + 71993 = 72036
- 53 + 71983 = 72036
- 73 + 71963 = 72036
- 89 + 71947 = 72036
- 103 + 71933 = 72036
Showing the first eight; more decompositions exist.
