Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472552, here are decompositions:

73 + 31472479 = 31472552
103 + 31472449 = 31472552
193 + 31472359 = 31472552
313 + 31472239 = 31472552
373 + 31472179 = 31472552
409 + 31472143 = 31472552
421 + 31472131 = 31472552
499 + 31472053 = 31472552

Showing the first eight; more decompositions exist.
