Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586102, here are decompositions:

43 + 31586059 = 31586102
139 + 31585963 = 31586102
199 + 31585903 = 31586102
439 + 31585663 = 31586102
523 + 31585579 = 31586102
601 + 31585501 = 31586102
643 + 31585459 = 31586102
661 + 31585441 = 31586102

Showing the first eight; more decompositions exist.
