Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574402, here are decompositions:

73 + 31574329 = 31574402
199 + 31574203 = 31574402
229 + 31574173 = 31574402
271 + 31574131 = 31574402
331 + 31574071 = 31574402
571 + 31573831 = 31574402
1009 + 31573393 = 31574402
1039 + 31573363 = 31574402

Showing the first eight; more decompositions exist.
