Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470132, here are decompositions:

59 + 31470073 = 31470132
179 + 31469953 = 31470132
229 + 31469903 = 31470132
271 + 31469861 = 31470132
283 + 31469849 = 31470132
349 + 31469783 = 31470132
401 + 31469731 = 31470132
409 + 31469723 = 31470132

Showing the first eight; more decompositions exist.
