Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987692, here are decompositions:

61 + 987631 = 987692
151 + 987541 = 987692
229 + 987463 = 987692
331 + 987361 = 987692
379 + 987313 = 987692
499 + 987193 = 987692
613 + 987079 = 987692
631 + 987061 = 987692

Showing the first eight; more decompositions exist.
