Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504652, here are decompositions:

61 + 31504591 = 31504652
79 + 31504573 = 31504652
199 + 31504453 = 31504652
349 + 31504303 = 31504652
433 + 31504219 = 31504652
463 + 31504189 = 31504652
523 + 31504129 = 31504652
601 + 31504051 = 31504652

Showing the first eight; more decompositions exist.
