Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506338, here are decompositions:

7 + 31506331 = 31506338
67 + 31506271 = 31506338
277 + 31506061 = 31506338
307 + 31506031 = 31506338
349 + 31505989 = 31506338
379 + 31505959 = 31506338
571 + 31505767 = 31506338
601 + 31505737 = 31506338

Showing the first eight; more decompositions exist.
