Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747746, here are decompositions:

3 + 8747743 = 8747746
23 + 8747723 = 8747746
167 + 8747579 = 8747746
173 + 8747573 = 8747746
233 + 8747513 = 8747746
257 + 8747489 = 8747746
263 + 8747483 = 8747746
419 + 8747327 = 8747746

Showing the first eight; more decompositions exist.
