Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493452, here are decompositions:

5 + 31493447 = 31493452
113 + 31493339 = 31493452
131 + 31493321 = 31493452
251 + 31493201 = 31493452
281 + 31493171 = 31493452
383 + 31493069 = 31493452
443 + 31493009 = 31493452
461 + 31492991 = 31493452

Showing the first eight; more decompositions exist.
