Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582698, here are decompositions:

19 + 31582679 = 31582698
31 + 31582667 = 31582698
67 + 31582631 = 31582698
71 + 31582627 = 31582698
89 + 31582609 = 31582698
97 + 31582601 = 31582698
109 + 31582589 = 31582698
139 + 31582559 = 31582698

Showing the first eight; more decompositions exist.
