Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744542, here are decompositions:

5 + 8744537 = 8744542
29 + 8744513 = 8744542
83 + 8744459 = 8744542
281 + 8744261 = 8744542
353 + 8744189 = 8744542
461 + 8744081 = 8744542
479 + 8744063 = 8744542
509 + 8744033 = 8744542

Showing the first eight; more decompositions exist.
