Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580462, here are decompositions:

139 + 31580323 = 31580462
223 + 31580239 = 31580462
229 + 31580233 = 31580462
241 + 31580221 = 31580462
313 + 31580149 = 31580462
349 + 31580113 = 31580462
379 + 31580083 = 31580462
409 + 31580053 = 31580462

Showing the first eight; more decompositions exist.
