Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467802, here are decompositions:

83 + 31467719 = 31467802
251 + 31467551 = 31467802
263 + 31467539 = 31467802
269 + 31467533 = 31467802
293 + 31467509 = 31467802
383 + 31467419 = 31467802
491 + 31467311 = 31467802
599 + 31467203 = 31467802

Showing the first eight; more decompositions exist.
