Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142846, here are decompositions:
- 5 + 142841 = 142846
- 47 + 142799 = 142846
- 59 + 142787 = 142846
- 89 + 142757 = 142846
- 113 + 142733 = 142846
- 149 + 142697 = 142846
- 173 + 142673 = 142846
- 227 + 142619 = 142846
Showing the first eight; more decompositions exist.
