Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460452, here are decompositions:

11 + 31460441 = 31460452
53 + 31460399 = 31460452
83 + 31460369 = 31460452
113 + 31460339 = 31460452
131 + 31460321 = 31460452
173 + 31460279 = 31460452
389 + 31460063 = 31460452
503 + 31459949 = 31460452

Showing the first eight; more decompositions exist.
