Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993642, here are decompositions:

31 + 993611 = 993642
53 + 993589 = 993642
101 + 993541 = 993642
149 + 993493 = 993642
163 + 993479 = 993642
191 + 993451 = 993642
211 + 993431 = 993642
241 + 993401 = 993642

Showing the first eight; more decompositions exist.
