Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470062, here are decompositions:

73 + 31469989 = 31470062
109 + 31469953 = 31470062
139 + 31469923 = 31470062
331 + 31469731 = 31470062
373 + 31469689 = 31470062
409 + 31469653 = 31470062
433 + 31469629 = 31470062
439 + 31469623 = 31470062

Showing the first eight; more decompositions exist.
