Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678488, here are decompositions:
- 41 + 8678447 = 8678488
- 89 + 8678399 = 8678488
- 149 + 8678339 = 8678488
- 251 + 8678237 = 8678488
- 347 + 8678141 = 8678488
- 359 + 8678129 = 8678488
- 419 + 8678069 = 8678488
- 431 + 8678057 = 8678488
Showing the first eight; more decompositions exist.
