Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690144, here are decompositions:

103 + 8690041 = 8690144
157 + 8689987 = 8690144
163 + 8689981 = 8690144
367 + 8689777 = 8690144
433 + 8689711 = 8690144
457 + 8689687 = 8690144
487 + 8689657 = 8690144
571 + 8689573 = 8690144

Showing the first eight; more decompositions exist.
