Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741972, here are decompositions:

61 + 8741911 = 8741972
193 + 8741779 = 8741972
223 + 8741749 = 8741972
229 + 8741743 = 8741972
331 + 8741641 = 8741972
409 + 8741563 = 8741972
439 + 8741533 = 8741972
541 + 8741431 = 8741972

Showing the first eight; more decompositions exist.
