Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731492, here are decompositions:

59 + 8731433 = 8731492
149 + 8731343 = 8731492
179 + 8731313 = 8731492
191 + 8731301 = 8731492
281 + 8731211 = 8731492
353 + 8731139 = 8731492
383 + 8731109 = 8731492
389 + 8731103 = 8731492

Showing the first eight; more decompositions exist.
