Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61442, here are decompositions:
- 61 + 61381 = 61442
- 79 + 61363 = 61442
- 103 + 61339 = 61442
- 109 + 61333 = 61442
- 151 + 61291 = 61442
- 181 + 61261 = 61442
- 211 + 61231 = 61442
- 313 + 61129 = 61442
Showing the first eight; more decompositions exist.
