Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462274, here are decompositions:

7 + 31462267 = 31462274
271 + 31462003 = 31462274
313 + 31461961 = 31462274
331 + 31461943 = 31462274
433 + 31461841 = 31462274
457 + 31461817 = 31462274
463 + 31461811 = 31462274
577 + 31461697 = 31462274

Showing the first eight; more decompositions exist.
