Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465082, here are decompositions:

13 + 31465069 = 31465082
43 + 31465039 = 31465082
79 + 31465003 = 31465082
109 + 31464973 = 31465082
199 + 31464883 = 31465082
373 + 31464709 = 31465082
433 + 31464649 = 31465082
463 + 31464619 = 31465082

Showing the first eight; more decompositions exist.
