Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460752, here are decompositions:

23 + 31460729 = 31460752
269 + 31460483 = 31460752
311 + 31460441 = 31460752
353 + 31460399 = 31460752
383 + 31460369 = 31460752
431 + 31460321 = 31460752
461 + 31460291 = 31460752
821 + 31459931 = 31460752

Showing the first eight; more decompositions exist.
