Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156278, here are decompositions:
- 19 + 156259 = 156278
- 37 + 156241 = 156278
- 61 + 156217 = 156278
- 127 + 156151 = 156278
- 139 + 156139 = 156278
- 151 + 156127 = 156278
- 271 + 156007 = 156278
- 457 + 155821 = 156278
Showing the first eight; more decompositions exist.
