Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462382, here are decompositions:

19 + 31462363 = 31462382
31 + 31462351 = 31462382
43 + 31462339 = 31462382
109 + 31462273 = 31462382
241 + 31462141 = 31462382
313 + 31462069 = 31462382
379 + 31462003 = 31462382
421 + 31461961 = 31462382

Showing the first eight; more decompositions exist.
