Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111902, here are decompositions:

31 + 111871 = 111902
73 + 111829 = 111902
103 + 111799 = 111902
151 + 111751 = 111902
181 + 111721 = 111902
409 + 111493 = 111902
463 + 111439 = 111902
601 + 111301 = 111902

Showing the first eight; more decompositions exist.
