Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142590, here are decompositions:
- 17 + 142573 = 142590
- 23 + 142567 = 142590
- 31 + 142559 = 142590
- 37 + 142553 = 142590
- 43 + 142547 = 142590
- 47 + 142543 = 142590
- 53 + 142537 = 142590
- 61 + 142529 = 142590
Showing the first eight; more decompositions exist.
