Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515058, here are decompositions:

11 + 31515047 = 31515058
17 + 31515041 = 31515058
59 + 31514999 = 31515058
89 + 31514969 = 31515058
269 + 31514789 = 31515058
317 + 31514741 = 31515058
431 + 31514627 = 31515058
479 + 31514579 = 31515058

Showing the first eight; more decompositions exist.
