Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147872, here are decompositions:
- 13 + 147859 = 147872
- 19 + 147853 = 147872
- 61 + 147811 = 147872
- 73 + 147799 = 147872
- 79 + 147793 = 147872
- 103 + 147769 = 147872
- 163 + 147709 = 147872
- 199 + 147673 = 147872
Showing the first eight; more decompositions exist.
