Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72032, here are decompositions:
- 13 + 72019 = 72032
- 61 + 71971 = 72032
- 151 + 71881 = 72032
- 211 + 71821 = 72032
- 223 + 71809 = 72032
- 271 + 71761 = 72032
- 313 + 71719 = 72032
- 439 + 71593 = 72032
Showing the first eight; more decompositions exist.
