Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625742, here are decompositions:

53 + 8625689 = 8625742
101 + 8625641 = 8625742
233 + 8625509 = 8625742
263 + 8625479 = 8625742
311 + 8625431 = 8625742
383 + 8625359 = 8625742
431 + 8625311 = 8625742
479 + 8625263 = 8625742

Showing the first eight; more decompositions exist.
