Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450076, here are decompositions:

19 + 31450057 = 31450076
43 + 31450033 = 31450076
109 + 31449967 = 31450076
139 + 31449937 = 31450076
223 + 31449853 = 31450076
337 + 31449739 = 31450076
379 + 31449697 = 31450076
397 + 31449679 = 31450076

Showing the first eight; more decompositions exist.
