Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72338, here are decompositions:
- 31 + 72307 = 72338
- 61 + 72277 = 72338
- 67 + 72271 = 72338
- 109 + 72229 = 72338
- 127 + 72211 = 72338
- 199 + 72139 = 72338
- 229 + 72109 = 72338
- 307 + 72031 = 72338
Showing the first eight; more decompositions exist.
