Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61544, here are decompositions:
- 37 + 61507 = 61544
- 61 + 61483 = 61544
- 73 + 61471 = 61544
- 103 + 61441 = 61544
- 127 + 61417 = 61544
- 163 + 61381 = 61544
- 181 + 61363 = 61544
- 211 + 61333 = 61544
Showing the first eight; more decompositions exist.
