Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988994, here are decompositions:

31 + 988963 = 988994
43 + 988951 = 988994
157 + 988837 = 988994
211 + 988783 = 988994
283 + 988711 = 988994
313 + 988681 = 988994
541 + 988453 = 988994
577 + 988417 = 988994

Showing the first eight; more decompositions exist.
