Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505702, here are decompositions:

43 + 31505659 = 31505702
79 + 31505623 = 31505702
103 + 31505599 = 31505702
181 + 31505521 = 31505702
229 + 31505473 = 31505702
271 + 31505431 = 31505702
331 + 31505371 = 31505702
373 + 31505329 = 31505702

Showing the first eight; more decompositions exist.
