Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723442, here are decompositions:

5 + 8723437 = 8723442
19 + 8723423 = 8723442
23 + 8723419 = 8723442
43 + 8723399 = 8723442
83 + 8723359 = 8723442
89 + 8723353 = 8723442
131 + 8723311 = 8723442
139 + 8723303 = 8723442

Showing the first eight; more decompositions exist.
