Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020902, here are decompositions:

61 + 1020841 = 1020902
79 + 1020823 = 1020902
151 + 1020751 = 1020902
193 + 1020709 = 1020902
271 + 1020631 = 1020902
283 + 1020619 = 1020902
313 + 1020589 = 1020902
373 + 1020529 = 1020902

Showing the first eight; more decompositions exist.
