Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749412, here are decompositions:

103 + 8749309 = 8749412
193 + 8749219 = 8749412
271 + 8749141 = 8749412
421 + 8748991 = 8749412
433 + 8748979 = 8749412
439 + 8748973 = 8749412
523 + 8748889 = 8749412
571 + 8748841 = 8749412

Showing the first eight; more decompositions exist.
