Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731442, here are decompositions:

61 + 8731381 = 8731442
73 + 8731369 = 8731442
79 + 8731363 = 8731442
103 + 8731339 = 8731442
193 + 8731249 = 8731442
211 + 8731231 = 8731442
229 + 8731213 = 8731442
241 + 8731201 = 8731442

Showing the first eight; more decompositions exist.
