Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502348, here are decompositions:

19 + 31502329 = 31502348
37 + 31502311 = 31502348
61 + 31502287 = 31502348
79 + 31502269 = 31502348
487 + 31501861 = 31502348
499 + 31501849 = 31502348
541 + 31501807 = 31502348
607 + 31501741 = 31502348

Showing the first eight; more decompositions exist.
