Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740486, here are decompositions:

59 + 8740427 = 8740486
113 + 8740373 = 8740486
149 + 8740337 = 8740486
197 + 8740289 = 8740486
317 + 8740169 = 8740486
347 + 8740139 = 8740486
389 + 8740097 = 8740486
449 + 8740037 = 8740486

Showing the first eight; more decompositions exist.
