Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470244, here are decompositions:

23 + 31470221 = 31470244
101 + 31470143 = 31470244
257 + 31469987 = 31470244
383 + 31469861 = 31470244
431 + 31469813 = 31470244
461 + 31469783 = 31470244
503 + 31469741 = 31470244
521 + 31469723 = 31470244

Showing the first eight; more decompositions exist.
