Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672090, here are decompositions:

3 + 8672087 = 8672090
43 + 8672047 = 8672090
103 + 8671987 = 8672090
109 + 8671981 = 8672090
379 + 8671711 = 8672090
421 + 8671669 = 8672090
457 + 8671633 = 8672090
541 + 8671549 = 8672090

Showing the first eight; more decompositions exist.
