Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464248, here are decompositions:

61 + 31464187 = 31464248
181 + 31464067 = 31464248
307 + 31463941 = 31464248
337 + 31463911 = 31464248
421 + 31463827 = 31464248
661 + 31463587 = 31464248
859 + 31463389 = 31464248
919 + 31463329 = 31464248

Showing the first eight; more decompositions exist.
