Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71072, here are decompositions:
- 3 + 71069 = 71072
- 13 + 71059 = 71072
- 61 + 71011 = 71072
- 73 + 70999 = 71072
- 103 + 70969 = 71072
- 151 + 70921 = 71072
- 181 + 70891 = 71072
- 193 + 70879 = 71072
Showing the first eight; more decompositions exist.
