Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735172, here are decompositions:

59 + 8735113 = 8735172
179 + 8734993 = 8735172
191 + 8734981 = 8735172
331 + 8734841 = 8735172
349 + 8734823 = 8735172
353 + 8734819 = 8735172
431 + 8734741 = 8735172
443 + 8734729 = 8735172

Showing the first eight; more decompositions exist.
