Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492052, here are decompositions:

19 + 31492033 = 31492052
139 + 31491913 = 31492052
211 + 31491841 = 31492052
373 + 31491679 = 31492052
433 + 31491619 = 31492052
439 + 31491613 = 31492052
463 + 31491589 = 31492052
541 + 31491511 = 31492052

Showing the first eight; more decompositions exist.
