Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972722, here are decompositions:

43 + 972679 = 972722
61 + 972661 = 972722
73 + 972649 = 972722
109 + 972613 = 972722
229 + 972493 = 972722
241 + 972481 = 972722
313 + 972409 = 972722
349 + 972373 = 972722

Showing the first eight; more decompositions exist.
