Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732390, here are decompositions:

19 + 8732371 = 8732390
151 + 8732239 = 8732390
181 + 8732209 = 8732390
193 + 8732197 = 8732390
367 + 8732023 = 8732390
397 + 8731993 = 8732390
409 + 8731981 = 8732390
439 + 8731951 = 8732390

Showing the first eight; more decompositions exist.
