Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537204, here are decompositions:

3 + 31537201 = 31537204
53 + 31537151 = 31537204
71 + 31537133 = 31537204
107 + 31537097 = 31537204
383 + 31536821 = 31537204
431 + 31536773 = 31537204
653 + 31536551 = 31537204
683 + 31536521 = 31537204

Showing the first eight; more decompositions exist.
