Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 132572, here are decompositions:
- 31 + 132541 = 132572
- 43 + 132529 = 132572
- 61 + 132511 = 132572
- 73 + 132499 = 132572
- 103 + 132469 = 132572
- 151 + 132421 = 132572
- 163 + 132409 = 132572
- 211 + 132361 = 132572
Showing the first eight; more decompositions exist.
