Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61790, here are decompositions:
- 61 + 61729 = 61790
- 67 + 61723 = 61790
- 73 + 61717 = 61790
- 103 + 61687 = 61790
- 109 + 61681 = 61790
- 139 + 61651 = 61790
- 163 + 61627 = 61790
- 181 + 61609 = 61790
Showing the first eight; more decompositions exist.
