Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534042, here are decompositions:

83 + 31533959 = 31534042
131 + 31533911 = 31534042
251 + 31533791 = 31534042
269 + 31533773 = 31534042
383 + 31533659 = 31534042
401 + 31533641 = 31534042
431 + 31533611 = 31534042
443 + 31533599 = 31534042

Showing the first eight; more decompositions exist.
