Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532362, here are decompositions:

23 + 31532339 = 31532362
83 + 31532279 = 31532362
101 + 31532261 = 31532362
359 + 31532003 = 31532362
431 + 31531931 = 31532362
479 + 31531883 = 31532362
683 + 31531679 = 31532362
839 + 31531523 = 31532362

Showing the first eight; more decompositions exist.
