Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470338, here are decompositions:

79 + 31470259 = 31470338
139 + 31470199 = 31470338
241 + 31470097 = 31470338
271 + 31470067 = 31470338
349 + 31469989 = 31470338
541 + 31469797 = 31470338
577 + 31469761 = 31470338
607 + 31469731 = 31470338

Showing the first eight; more decompositions exist.
