Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509058, here are decompositions:

5 + 31509053 = 31509058
29 + 31509029 = 31509058
41 + 31509017 = 31509058
59 + 31508999 = 31509058
137 + 31508921 = 31509058
311 + 31508747 = 31509058
401 + 31508657 = 31509058
419 + 31508639 = 31509058

Showing the first eight; more decompositions exist.
