Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703780, here are decompositions:

37 + 8703743 = 8703780
61 + 8703719 = 8703780
139 + 8703641 = 8703780
149 + 8703631 = 8703780
157 + 8703623 = 8703780
167 + 8703613 = 8703780
191 + 8703589 = 8703780
199 + 8703581 = 8703780

Showing the first eight; more decompositions exist.
