Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533742, here are decompositions:

83 + 31533659 = 31533742
101 + 31533641 = 31533742
131 + 31533611 = 31533742
179 + 31533563 = 31533742
281 + 31533461 = 31533742
293 + 31533449 = 31533742
311 + 31533431 = 31533742
353 + 31533389 = 31533742

Showing the first eight; more decompositions exist.
