Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621402, here are decompositions:

103 + 8621299 = 8621402
193 + 8621209 = 8621402
313 + 8621089 = 8621402
409 + 8620993 = 8621402
541 + 8620861 = 8621402
739 + 8620663 = 8621402
859 + 8620543 = 8621402
1009 + 8620393 = 8621402

Showing the first eight; more decompositions exist.
