Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464394, here are decompositions:

53 + 31464341 = 31464394
113 + 31464281 = 31464394
251 + 31464143 = 31464394
257 + 31464137 = 31464394
347 + 31464047 = 31464394
431 + 31463963 = 31464394
503 + 31463891 = 31464394
587 + 31463807 = 31464394

Showing the first eight; more decompositions exist.
