Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499134, here are decompositions:

71 + 31499063 = 31499134
101 + 31499033 = 31499134
113 + 31499021 = 31499134
131 + 31499003 = 31499134
167 + 31498967 = 31499134
281 + 31498853 = 31499134
431 + 31498703 = 31499134
587 + 31498547 = 31499134

Showing the first eight; more decompositions exist.
