Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732572, here are decompositions:

71 + 8732501 = 8732572
83 + 8732489 = 8732572
263 + 8732309 = 8732572
281 + 8732291 = 8732572
311 + 8732261 = 8732572
383 + 8732189 = 8732572
449 + 8732123 = 8732572
479 + 8732093 = 8732572

Showing the first eight; more decompositions exist.
