Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138232, here are decompositions:
- 23 + 138209 = 138232
- 41 + 138191 = 138232
- 53 + 138179 = 138232
- 89 + 138143 = 138232
- 131 + 138101 = 138232
- 173 + 138059 = 138232
- 179 + 138053 = 138232
- 191 + 138041 = 138232
Showing the first eight; more decompositions exist.
