Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742292, here are decompositions:

29 + 8742263 = 8742292
131 + 8742161 = 8742292
233 + 8742059 = 8742292
281 + 8742011 = 8742292
359 + 8741933 = 8742292
431 + 8741861 = 8742292
479 + 8741813 = 8742292
491 + 8741801 = 8742292

Showing the first eight; more decompositions exist.
