Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472434, here are decompositions:

83 + 31472351 = 31472434
173 + 31472261 = 31472434
233 + 31472201 = 31472434
251 + 31472183 = 31472434
281 + 31472153 = 31472434
311 + 31472123 = 31472434
431 + 31472003 = 31472434
443 + 31471991 = 31472434

Showing the first eight; more decompositions exist.
