Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988784, here are decompositions:

73 + 988711 = 988784
103 + 988681 = 988784
193 + 988591 = 988784
283 + 988501 = 988784
331 + 988453 = 988784
367 + 988417 = 988784
463 + 988321 = 988784
487 + 988297 = 988784

Showing the first eight; more decompositions exist.
