Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942800, here are decompositions:

13 + 942787 = 942800
37 + 942763 = 942800
73 + 942727 = 942800
109 + 942691 = 942800
139 + 942661 = 942800
163 + 942637 = 942800
193 + 942607 = 942800
223 + 942577 = 942800

Showing the first eight; more decompositions exist.
