Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582702, here are decompositions:

23 + 31582679 = 31582702
29 + 31582673 = 31582702
71 + 31582631 = 31582702
89 + 31582613 = 31582702
101 + 31582601 = 31582702
113 + 31582589 = 31582702
149 + 31582553 = 31582702
293 + 31582409 = 31582702

Showing the first eight; more decompositions exist.
