Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740240, here are decompositions:

53 + 8740187 = 8740240
71 + 8740169 = 8740240
83 + 8740157 = 8740240
101 + 8740139 = 8740240
389 + 8739851 = 8740240
419 + 8739821 = 8740240
491 + 8739749 = 8740240
569 + 8739671 = 8740240

Showing the first eight; more decompositions exist.
