Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470292, here are decompositions:

71 + 31470221 = 31470292
83 + 31470209 = 31470292
149 + 31470143 = 31470292
389 + 31469903 = 31470292
431 + 31469861 = 31470292
443 + 31469849 = 31470292
479 + 31469813 = 31470292
509 + 31469783 = 31470292

Showing the first eight; more decompositions exist.
