Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 44172, here are decompositions:
- 13 + 44159 = 44172
- 41 + 44131 = 44172
- 43 + 44129 = 44172
- 53 + 44119 = 44172
- 61 + 44111 = 44172
- 71 + 44101 = 44172
- 83 + 44089 = 44172
- 101 + 44071 = 44172
Showing the first eight; more decompositions exist.
