Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496558, here are decompositions:

7 + 31496551 = 31496558
19 + 31496539 = 31496558
109 + 31496449 = 31496558
139 + 31496419 = 31496558
229 + 31496329 = 31496558
241 + 31496317 = 31496558
337 + 31496221 = 31496558
349 + 31496209 = 31496558

Showing the first eight; more decompositions exist.
