Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582118, here are decompositions:

97 + 31582021 = 31582118
157 + 31581961 = 31582118
229 + 31581889 = 31582118
241 + 31581877 = 31582118
331 + 31581787 = 31582118
409 + 31581709 = 31582118
439 + 31581679 = 31582118
571 + 31581547 = 31582118

Showing the first eight; more decompositions exist.
