Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748146, here are decompositions:

3 + 8748143 = 8748146
37 + 8748109 = 8748146
103 + 8748043 = 8748146
229 + 8747917 = 8748146
283 + 8747863 = 8748146
409 + 8747737 = 8748146
457 + 8747689 = 8748146
523 + 8747623 = 8748146

Showing the first eight; more decompositions exist.
