Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447514, here are decompositions:

37 + 31447477 = 31447514
73 + 31447441 = 31447514
151 + 31447363 = 31447514
157 + 31447357 = 31447514
181 + 31447333 = 31447514
433 + 31447081 = 31447514
487 + 31447027 = 31447514
541 + 31446973 = 31447514

Showing the first eight; more decompositions exist.
