Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464542, here are decompositions:

61 + 31464481 = 31464542
79 + 31464463 = 31464542
103 + 31464439 = 31464542
271 + 31464271 = 31464542
349 + 31464193 = 31464542
463 + 31464079 = 31464542
541 + 31464001 = 31464542
601 + 31463941 = 31464542

Showing the first eight; more decompositions exist.
