Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460368, here are decompositions:

29 + 31460339 = 31460368
47 + 31460321 = 31460368
89 + 31460279 = 31460368
101 + 31460267 = 31460368
239 + 31460129 = 31460368
419 + 31459949 = 31460368
431 + 31459937 = 31460368
509 + 31459859 = 31460368

Showing the first eight; more decompositions exist.
