Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79972, here are decompositions:
- 5 + 79967 = 79972
- 29 + 79943 = 79972
- 71 + 79901 = 79972
- 83 + 79889 = 79972
- 131 + 79841 = 79972
- 149 + 79823 = 79972
- 281 + 79691 = 79972
- 359 + 79613 = 79972
Showing the first eight; more decompositions exist.
