Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127436, here are decompositions:

13 + 127423 = 127436
37 + 127399 = 127436
73 + 127363 = 127436
139 + 127297 = 127436
229 + 127207 = 127436
313 + 127123 = 127436
487 + 126949 = 127436
523 + 126913 = 127436

Showing the first eight; more decompositions exist.
