Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504586, here are decompositions:

13 + 31504573 = 31504586
19 + 31504567 = 31504586
199 + 31504387 = 31504586
229 + 31504357 = 31504586
283 + 31504303 = 31504586
367 + 31504219 = 31504586
397 + 31504189 = 31504586
457 + 31504129 = 31504586

Showing the first eight; more decompositions exist.
