Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737972, here are decompositions:

29 + 8737943 = 8737972
101 + 8737871 = 8737972
263 + 8737709 = 8737972
389 + 8737583 = 8737972
401 + 8737571 = 8737972
443 + 8737529 = 8737972
449 + 8737523 = 8737972
491 + 8737481 = 8737972

Showing the first eight; more decompositions exist.
