Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506752, here are decompositions:

3 + 31506749 = 31506752
223 + 31506529 = 31506752
229 + 31506523 = 31506752
241 + 31506511 = 31506752
331 + 31506421 = 31506752
379 + 31506373 = 31506752
421 + 31506331 = 31506752
661 + 31506091 = 31506752

Showing the first eight; more decompositions exist.
