Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590798, here are decompositions:

7 + 31590791 = 31590798
59 + 31590739 = 31590798
61 + 31590737 = 31590798
67 + 31590731 = 31590798
131 + 31590667 = 31590798
139 + 31590659 = 31590798
149 + 31590649 = 31590798
167 + 31590631 = 31590798

Showing the first eight; more decompositions exist.
