Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147690, here are decompositions:
- 17 + 147673 = 147690
- 19 + 147671 = 147690
- 29 + 147661 = 147690
- 43 + 147647 = 147690
- 61 + 147629 = 147690
- 73 + 147617 = 147690
- 83 + 147607 = 147690
- 107 + 147583 = 147690
Showing the first eight; more decompositions exist.
