Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506424, here are decompositions:

3 + 31506421 = 31506424
71 + 31506353 = 31506424
113 + 31506311 = 31506424
251 + 31506173 = 31506424
353 + 31506071 = 31506424
431 + 31505993 = 31506424
503 + 31505921 = 31506424
617 + 31505807 = 31506424

Showing the first eight; more decompositions exist.
