Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8132, here are decompositions:
- 31 + 8101 = 8132
- 43 + 8089 = 8132
- 73 + 8059 = 8132
- 79 + 8053 = 8132
- 139 + 7993 = 8132
- 181 + 7951 = 8132
- 199 + 7933 = 8132
- 373 + 7759 = 8132
Showing the first eight; more decompositions exist.
