Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558034, here are decompositions:

37 + 31557997 = 31558034
73 + 31557961 = 31558034
97 + 31557937 = 31558034
103 + 31557931 = 31558034
223 + 31557811 = 31558034
331 + 31557703 = 31558034
337 + 31557697 = 31558034
397 + 31557637 = 31558034

Showing the first eight; more decompositions exist.
