Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737042, here are decompositions:

3 + 8737039 = 8737042
53 + 8736989 = 8737042
131 + 8736911 = 8737042
233 + 8736809 = 8737042
359 + 8736683 = 8737042
383 + 8736659 = 8737042
389 + 8736653 = 8737042
449 + 8736593 = 8737042

Showing the first eight; more decompositions exist.
