Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72282, here are decompositions:
- 5 + 72277 = 72282
- 11 + 72271 = 72282
- 13 + 72269 = 72282
- 29 + 72253 = 72282
- 31 + 72251 = 72282
- 53 + 72229 = 72282
- 59 + 72223 = 72282
- 61 + 72221 = 72282
Showing the first eight; more decompositions exist.
