Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742232, here are decompositions:

71 + 8742161 = 8742232
173 + 8742059 = 8742232
281 + 8741951 = 8742232
419 + 8741813 = 8742232
431 + 8741801 = 8742232
479 + 8741753 = 8742232
491 + 8741741 = 8742232
593 + 8741639 = 8742232

Showing the first eight; more decompositions exist.
