Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72430, here are decompositions:

47 + 72383 = 72430
89 + 72341 = 72430
179 + 72251 = 72430
257 + 72173 = 72430
263 + 72167 = 72430
269 + 72161 = 72430
353 + 72077 = 72430
383 + 72047 = 72430

Showing the first eight; more decompositions exist.
