Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690090, here are decompositions:

103 + 8689987 = 8690090
109 + 8689981 = 8690090
313 + 8689777 = 8690090
337 + 8689753 = 8690090
379 + 8689711 = 8690090
433 + 8689657 = 8690090
463 + 8689627 = 8690090
499 + 8689591 = 8690090

Showing the first eight; more decompositions exist.
