Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498742, here are decompositions:

3 + 498739 = 498742
53 + 498689 = 498742
89 + 498653 = 498742
131 + 498611 = 498742
191 + 498551 = 498742
281 + 498461 = 498742
599 + 498143 = 498742
641 + 498101 = 498742

Showing the first eight; more decompositions exist.
