Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454302, here are decompositions:

53 + 31454249 = 31454302
83 + 31454219 = 31454302
101 + 31454201 = 31454302
179 + 31454123 = 31454302
311 + 31453991 = 31454302
359 + 31453943 = 31454302
419 + 31453883 = 31454302
461 + 31453841 = 31454302

Showing the first eight; more decompositions exist.
