Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722742, here are decompositions:

3 + 8722739 = 8722742
31 + 8722711 = 8722742
139 + 8722603 = 8722742
271 + 8722471 = 8722742
283 + 8722459 = 8722742
313 + 8722429 = 8722742
349 + 8722393 = 8722742
409 + 8722333 = 8722742

Showing the first eight; more decompositions exist.
