Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61490, here are decompositions:
- 3 + 61487 = 61490
- 7 + 61483 = 61490
- 19 + 61471 = 61490
- 73 + 61417 = 61490
- 109 + 61381 = 61490
- 127 + 61363 = 61490
- 151 + 61339 = 61490
- 157 + 61333 = 61490
Showing the first eight; more decompositions exist.
