Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72044, here are decompositions:
- 13 + 72031 = 72044
- 61 + 71983 = 72044
- 73 + 71971 = 72044
- 97 + 71947 = 72044
- 103 + 71941 = 72044
- 127 + 71917 = 72044
- 157 + 71887 = 72044
- 163 + 71881 = 72044
Showing the first eight; more decompositions exist.
