Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988742, here are decompositions:

31 + 988711 = 988742
61 + 988681 = 988742
151 + 988591 = 988742
163 + 988579 = 988742
193 + 988549 = 988742
241 + 988501 = 988742
283 + 988459 = 988742
421 + 988321 = 988742

Showing the first eight; more decompositions exist.
