Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72402, here are decompositions:
- 19 + 72383 = 72402
- 23 + 72379 = 72402
- 61 + 72341 = 72402
- 89 + 72313 = 72402
- 131 + 72271 = 72402
- 149 + 72253 = 72402
- 151 + 72251 = 72402
- 173 + 72229 = 72402
Showing the first eight; more decompositions exist.
