Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753642, here are decompositions:

61 + 8753581 = 8753642
103 + 8753539 = 8753642
181 + 8753461 = 8753642
193 + 8753449 = 8753642
199 + 8753443 = 8753642
241 + 8753401 = 8753642
283 + 8753359 = 8753642
349 + 8753293 = 8753642

Showing the first eight; more decompositions exist.
