Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749742, here are decompositions:

73 + 8749669 = 8749742
139 + 8749603 = 8749742
163 + 8749579 = 8749742
193 + 8749549 = 8749742
433 + 8749309 = 8749742
499 + 8749243 = 8749742
523 + 8749219 = 8749742
601 + 8749141 = 8749742

Showing the first eight; more decompositions exist.
