Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61730, here are decompositions:
- 7 + 61723 = 61730
- 13 + 61717 = 61730
- 43 + 61687 = 61730
- 73 + 61657 = 61730
- 79 + 61651 = 61730
- 103 + 61627 = 61730
- 127 + 61603 = 61730
- 211 + 61519 = 61730
Showing the first eight; more decompositions exist.
