Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146478, here are decompositions:

29 + 146449 = 146478
41 + 146437 = 146478
61 + 146417 = 146478
71 + 146407 = 146478
89 + 146389 = 146478
97 + 146381 = 146478
109 + 146369 = 146478
131 + 146347 = 146478

Showing the first eight; more decompositions exist.
