Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740420, here are decompositions:

47 + 8740373 = 8740420
53 + 8740367 = 8740420
83 + 8740337 = 8740420
89 + 8740331 = 8740420
131 + 8740289 = 8740420
233 + 8740187 = 8740420
251 + 8740169 = 8740420
257 + 8740163 = 8740420

Showing the first eight; more decompositions exist.
