Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147072, here are decompositions:
- 41 + 147031 = 147072
- 43 + 147029 = 147072
- 61 + 147011 = 147072
- 83 + 146989 = 147072
- 89 + 146983 = 147072
- 131 + 146941 = 147072
- 139 + 146933 = 147072
- 151 + 146921 = 147072
Showing the first eight; more decompositions exist.
