Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461436, here are decompositions:

23 + 31461413 = 31461436
257 + 31461179 = 31461436
263 + 31461173 = 31461436
389 + 31461047 = 31461436
509 + 31460927 = 31461436
557 + 31460879 = 31461436
563 + 31460873 = 31461436
599 + 31460837 = 31461436

Showing the first eight; more decompositions exist.
