Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152572, here are decompositions:
- 5 + 152567 = 152572
- 41 + 152531 = 152572
- 53 + 152519 = 152572
- 71 + 152501 = 152572
- 113 + 152459 = 152572
- 131 + 152441 = 152572
- 149 + 152423 = 152572
- 179 + 152393 = 152572
Showing the first eight; more decompositions exist.
