Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42884, here are decompositions:

31 + 42853 = 42884
43 + 42841 = 42884
97 + 42787 = 42884
157 + 42727 = 42884
181 + 42703 = 42884
241 + 42643 = 42884
307 + 42577 = 42884
313 + 42571 = 42884

Showing the first eight; more decompositions exist.
