Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748158, here are decompositions:

61 + 8748097 = 8748158
127 + 8748031 = 8748158
157 + 8748001 = 8748158
229 + 8747929 = 8748158
241 + 8747917 = 8748158
421 + 8747737 = 8748158
457 + 8747701 = 8748158
541 + 8747617 = 8748158

Showing the first eight; more decompositions exist.
