Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506074, here are decompositions:

3 + 31506071 = 31506074
13 + 31506061 = 31506074
43 + 31506031 = 31506074
151 + 31505923 = 31506074
307 + 31505767 = 31506074
337 + 31505737 = 31506074
373 + 31505701 = 31506074
541 + 31505533 = 31506074

Showing the first eight; more decompositions exist.
