Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558052, here are decompositions:

3 + 31558049 = 31558052
13 + 31558039 = 31558052
241 + 31557811 = 31558052
349 + 31557703 = 31558052
499 + 31557553 = 31558052
523 + 31557529 = 31558052
541 + 31557511 = 31558052
619 + 31557433 = 31558052

Showing the first eight; more decompositions exist.
