Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474402, here are decompositions:

5 + 31474397 = 31474402
59 + 31474343 = 31474402
83 + 31474319 = 31474402
101 + 31474301 = 31474402
149 + 31474253 = 31474402
359 + 31474043 = 31474402
431 + 31473971 = 31474402
563 + 31473839 = 31474402

Showing the first eight; more decompositions exist.
