Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988542, here are decompositions:

31 + 988511 = 988542
41 + 988501 = 988542
53 + 988489 = 988542
59 + 988483 = 988542
83 + 988459 = 988542
89 + 988453 = 988542
103 + 988439 = 988542
199 + 988343 = 988542

Showing the first eight; more decompositions exist.
