Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61400, here are decompositions:
- 19 + 61381 = 61400
- 37 + 61363 = 61400
- 43 + 61357 = 61400
- 61 + 61339 = 61400
- 67 + 61333 = 61400
- 103 + 61297 = 61400
- 109 + 61291 = 61400
- 139 + 61261 = 61400
Showing the first eight; more decompositions exist.
