Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460398, here are decompositions:

29 + 31460369 = 31460398
59 + 31460339 = 31460398
107 + 31460291 = 31460398
131 + 31460267 = 31460398
269 + 31460129 = 31460398
449 + 31459949 = 31460398
461 + 31459937 = 31460398
467 + 31459931 = 31460398

Showing the first eight; more decompositions exist.
