Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462404, here are decompositions:

23 + 31462381 = 31462404
31 + 31462373 = 31462404
41 + 31462363 = 31462404
47 + 31462357 = 31462404
53 + 31462351 = 31462404
131 + 31462273 = 31462404
137 + 31462267 = 31462404
263 + 31462141 = 31462404

Showing the first eight; more decompositions exist.
