Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731406, here are decompositions:

37 + 8731369 = 8731406
43 + 8731363 = 8731406
67 + 8731339 = 8731406
97 + 8731309 = 8731406
157 + 8731249 = 8731406
193 + 8731213 = 8731406
337 + 8731069 = 8731406
367 + 8731039 = 8731406

Showing the first eight; more decompositions exist.
