Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611466, here are decompositions:

137 + 31611329 = 31611466
167 + 31611299 = 31611466
353 + 31611113 = 31611466
443 + 31611023 = 31611466
449 + 31611017 = 31611466
599 + 31610867 = 31611466
743 + 31610723 = 31611466
827 + 31610639 = 31611466

Showing the first eight; more decompositions exist.
