Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465052, here are decompositions:

13 + 31465039 = 31465052
19 + 31465033 = 31465052
61 + 31464991 = 31465052
79 + 31464973 = 31465052
271 + 31464781 = 31465052
433 + 31464619 = 31465052
571 + 31464481 = 31465052
601 + 31464451 = 31465052

Showing the first eight; more decompositions exist.
