Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747492, here are decompositions:

3 + 8747489 = 8747492
73 + 8747419 = 8747492
163 + 8747329 = 8747492
241 + 8747251 = 8747492
373 + 8747119 = 8747492
409 + 8747083 = 8747492
421 + 8747071 = 8747492
571 + 8746921 = 8747492

Showing the first eight; more decompositions exist.
