Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590834, here are decompositions:

31 + 31590803 = 31590834
43 + 31590791 = 31590834
71 + 31590763 = 31590834
97 + 31590737 = 31590834
101 + 31590733 = 31590834
103 + 31590731 = 31590834
151 + 31590683 = 31590834
167 + 31590667 = 31590834

Showing the first eight; more decompositions exist.
