Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502054, here are decompositions:

97 + 31501957 = 31502054
193 + 31501861 = 31502054
223 + 31501831 = 31502054
313 + 31501741 = 31502054
421 + 31501633 = 31502054
433 + 31501621 = 31502054
487 + 31501567 = 31502054
523 + 31501531 = 31502054

Showing the first eight; more decompositions exist.
