Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731436, here are decompositions:

3 + 8731433 = 8731436
19 + 8731417 = 8731436
67 + 8731369 = 8731436
73 + 8731363 = 8731436
97 + 8731339 = 8731436
127 + 8731309 = 8731436
223 + 8731213 = 8731436
283 + 8731153 = 8731436

Showing the first eight; more decompositions exist.
