Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 132440, here are decompositions:
- 3 + 132437 = 132440
- 19 + 132421 = 132440
- 31 + 132409 = 132440
- 37 + 132403 = 132440
- 73 + 132367 = 132440
- 79 + 132361 = 132440
- 109 + 132331 = 132440
- 127 + 132313 = 132440
Showing the first eight; more decompositions exist.
