Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496950, here are decompositions:

3 + 31496947 = 31496950
29 + 31496921 = 31496950
131 + 31496819 = 31496950
167 + 31496783 = 31496950
257 + 31496693 = 31496950
281 + 31496669 = 31496950
383 + 31496567 = 31496950
431 + 31496519 = 31496950

Showing the first eight; more decompositions exist.
