Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002812, here are decompositions:

3 + 1002809 = 1002812
43 + 1002769 = 1002812
61 + 1002751 = 1002812
73 + 1002739 = 1002812
103 + 1002709 = 1002812
193 + 1002619 = 1002812
229 + 1002583 = 1002812
331 + 1002481 = 1002812

Showing the first eight; more decompositions exist.
