Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461752, here are decompositions:

79 + 31461673 = 31461752
181 + 31461571 = 31461752
199 + 31461553 = 31461752
229 + 31461523 = 31461752
271 + 31461481 = 31461752
349 + 31461403 = 31461752
409 + 31461343 = 31461752
499 + 31461253 = 31461752

Showing the first eight; more decompositions exist.
