Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540510, here are decompositions:

11 + 31540499 = 31540510
17 + 31540493 = 31540510
167 + 31540343 = 31540510
269 + 31540241 = 31540510
293 + 31540217 = 31540510
347 + 31540163 = 31540510
401 + 31540109 = 31540510
479 + 31540031 = 31540510

Showing the first eight; more decompositions exist.
