Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480058, here are decompositions:

37 + 31480021 = 31480058
97 + 31479961 = 31480058
109 + 31479949 = 31480058
229 + 31479829 = 31480058
241 + 31479817 = 31480058
409 + 31479649 = 31480058
439 + 31479619 = 31480058
499 + 31479559 = 31480058

Showing the first eight; more decompositions exist.
