Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452496, here are decompositions:

3 + 31452493 = 31452496
263 + 31452233 = 31452496
293 + 31452203 = 31452496
359 + 31452137 = 31452496
503 + 31451993 = 31452496
587 + 31451909 = 31452496
659 + 31451837 = 31452496
743 + 31451753 = 31452496

Showing the first eight; more decompositions exist.
