Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61610, here are decompositions:
- 7 + 61603 = 61610
- 67 + 61543 = 61610
- 103 + 61507 = 61610
- 127 + 61483 = 61610
- 139 + 61471 = 61610
- 193 + 61417 = 61610
- 229 + 61381 = 61610
- 271 + 61339 = 61610
Showing the first eight; more decompositions exist.
