Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748142, here are decompositions:

5 + 8748137 = 8748142
131 + 8748011 = 8748142
239 + 8747903 = 8748142
251 + 8747891 = 8748142
311 + 8747831 = 8748142
353 + 8747789 = 8748142
383 + 8747759 = 8748142
419 + 8747723 = 8748142

Showing the first eight; more decompositions exist.
