Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72444, here are decompositions:
- 13 + 72431 = 72444
- 23 + 72421 = 72444
- 61 + 72383 = 72444
- 103 + 72341 = 72444
- 107 + 72337 = 72444
- 131 + 72313 = 72444
- 137 + 72307 = 72444
- 157 + 72287 = 72444
Showing the first eight; more decompositions exist.
