Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749274, here are decompositions:

31 + 8749243 = 8749274
67 + 8749207 = 8749274
283 + 8748991 = 8749274
397 + 8748877 = 8749274
421 + 8748853 = 8749274
433 + 8748841 = 8749274
463 + 8748811 = 8749274
487 + 8748787 = 8749274

Showing the first eight; more decompositions exist.
