Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462422, here are decompositions:

41 + 31462381 = 31462422
59 + 31462363 = 31462422
71 + 31462351 = 31462422
73 + 31462349 = 31462422
83 + 31462339 = 31462422
109 + 31462313 = 31462422
149 + 31462273 = 31462422
281 + 31462141 = 31462422

Showing the first eight; more decompositions exist.
